Description

LAMINATED CUT GLASS FIBER FOR AUTOMOTIVE TITLES AND MANUFACTURING METHOD. CROSS REFERENCE TO THE APPLICATION IN RELATIONSHIP. This is the continuation in part pending of the request of E.U. with serial No. 09 / 387,813 filed on September 1, 1999. BACKGROUND OF THE INVENTION. This invention relates to a tri-laminated cut glass fiber structure and to a manufacturing method, and more particularly to an improved and expanded cut glass fiber sheet for use in mouldable titles made from said structures for motor vehicles. . In prior art the constructions of moldable titles for motor vehicles and vans generally included a flexible phenol-saturated fiberglass cover molded into a shell. In a secondary step, a decorative fabric as an outer layer, usually a nylon tricot material reinforced with a 3mm foam layer is attached to the shell. The foam helps to hide imperfections in the fiberglass shell. The automotive industry has recently scrapped this construction and changed to an accepted European technology. This technology involves the use of a multi-layer composite including a foam core and two outer layers of cut fiberglass surrounding the foam core. The fiberglass is either cut in place or provided in a piece of flexible cloth and generally includes stamens of fiberglass in the form of cut filaments between 1.27 to 10.16 cm (1/2"to 4") long. This tri-laminate is saturated with an isocyanide resin which binds the layers during the molding process which forms the part in a figure to fit within a specific vehicle. The layers of fiberglass on the other side of the foam core are included to impart greater rigidity to the part of the title. The European triplex construction is usually then walled between the outer layers of the film. These layers of the film act as barriers to prevent the isocyanide resin liquid from penetrating through the top layer which is the decorative material. Similarly, the film layer in the back prevents the isocyanide from penetrating the removable layer of the reinforcing mold and contaminating it. If the adhesive liquid drips through the decorative material, it will be visible and will cause a rejection of the part, or it may cause it to stick or stick to the back side of the mold part. There are efforts in action in the automotive industry to provide moldable components for titles which show greater extension in both transverse and machine directions to facilitate manufacturing in severe curves and compensations during the healing process. The conventional glass layers added to improve the stiffness of the finished title are generally brittle, thus limiting the ultimate finish of the finished product. A commercial example of a sheet absorbing a sound is shown in the U.S. Patent. No. 4, 828, 910 for Haussling. Here the laminated structure includes a porous glass fabric cut as reinforcement attached to a fibrous flexible cotton sheet. A decorative fabric cover covers the exposed or the outer surface of the reinforcing fabric all joined by a thermoplastic resin binder. The flexible material covers by sandwiching the fibrous cotton sheet are glass fibers bonded by a thermoformable resin to impart the stiffness required to the finished title. Finally, a porous fabric of cotton fabric as a removable layer is adhesively secured to the back of the flexible reinforcing material by the thermosetting resin covering the flexible material. Another type of moldable automotive title is shown in the U.S. Patent. No. 4,840,832 to Weinle, et al. Here, the title is formed by a sheet formed of polymer fibers including at least a portion of potentially adhesive fibers. The finished title is characterized by a highly deformable flexible construction which facilitates installation in the vehicle. The fibers in the sheet are joined in a multiplicity of locations which imparts a self-supporting molded rigidity allowing the title to retain its shape when installed, a flexible foam layer is adhered to a surface to a flexible cotton sheet surface and the outer textile material is attached to the foam layer. Romesberg et. to the. in the US Patents No. 5, 486,256 and No. 5,582,906 disclose a typical title of I-ray foam core having a fiberglass layer cut on both sides of a foam core. The cut glass fiber is applied in a first glass cutting station on a belt of adhesive film which becomes the back layer of glass fiber and deposits a second layer of cut glass on the front of the foam layer in a second glass cutting station. A wet adhesive is then applied on the second layer of fiberglass and a decorative material is applied to the prior adhesive for molding. The U.S. Patent No. 5,591,289 to Souders, et al discloses another title based on a fibrous cotton sheet including binding fibers coated with a thermosetting resin to impart rigidity to the part. In the U.S. Patent No. 5,660,908 to Elman, et. to the. A Polyethylene Title (PET) is formed of a fibrous cotton fabric having a plurality of impressions which are filled with the PET spreader and attached to a PET cotton fabric to impart additional stiffness. While the available constructions produce adaptable compounds, constructions that include glass fibers to stiffen the finished product while remaining difficult to mold. Accordingly, it is desirable to provide a cut glass fiber laminate for a moldable title which will provide a compound for molding having at least 30 percent extension in both machine and cross direction, and will allow excellent conformation. for deep drawing areas when molding and will provide rigidity in the final product of the title.

Generally speaking, in accordance with this invention, a laminated fiberglass laminate for manufacturing moldable structures and laminate and title manufacturing methods are provided. The cut fiberglass laminate is formed by feeding a nonwoven continuous cotton fabric of a fine synthetic fiber and a non-porous barrier film through rolls. The cut fiberglass and the adhesive are deposited on the movable barrier film and the cotton fabric without being interlaced are then heated in an oven, passed through the pressure rollers, cooled and then interlaced in a roll form for its transportation and use. The laminated fiberglass laminate has elastic properties exceeding the breaking point by 30 to 40% in both machine and transverse directions. The fine synthetic fiber used in the cotton fabric without being interlaced is an interlaced fiber having a weave finish between 1.8 and 2.2 to impart the desired extension properties. A composite of the title is formed by combining the fiberglass laminate with a foam layer on the surface of the glass fiber, an additional layer on the surface of the glass fiber is placed on the opposite surface of the foam and a decorative fabric which may include a foam reinforcement is placed on the exposed surface of the fiberglass. This title compound is then ready to be molded. The high spread properties of the cut fiberglass laminate provide excellent conformation in the deep drawing areas in the mold. Accordingly, it is an object of the present invention to provide an embedded / fiberglass film / cut barrier containing a laminated structure having improved extension properties. Another object of the invention is to provide an improved cut glass fiber containing a laminate including a non-woven fabric formed of an interlaced synthetic fiber of great fineness. A further object of the invention is to provide an improved cut glass fiber containing a laminate including a non-woven fabric formed of an interlaced polyester fiber of between 1.8 and 2.2 fineness units. Still another object of the invention is to provide an improved cut glass fiber containing a laminate including a thermoplastic barrier film to adhere the glass fiber cut to it and providing a non-porous barrier to prevent contamination of the mold. The invention is to provide a method for manufacturing cut glass fiber containing a laminate with an elasticity exceeding the breaking point of 30% to 40% in both machine and transverse directions and the energy breaking point less than 201bf -in in any direction. Still another object of the invention is to provide a method for the formation of a non-woven / barrier fabric a laminated / cut fiberglass laminate which can be formed within a roll or sheet for easy storage and prior transport to be combined to form a compound of an automotive title. Still another object of the invention is to provide an apparatus for forming a non-woven / barrier fabric a film / cut of fiberglass laminate which can be stored in roll or sheet form. Still other objects of and advantages of the invention all in part are obvious and all in part will be apparent from the specification. According to the invention this includes several steps and the relationship of one or more of said steps with respect to each other, and the products which possess the characteristics, properties and relationship of the (compounds) constituents, all as exemplified in the detailed discussion hereinafter, and the vision of the invention will be indicated in the clauses. BRIEF DESCRIPTION OF THE DRAWINGS For a more complete understanding of the invention, the references given to the following description taken in connection with the accompanying drawings in which; FIGURE 1 is a top perspective view of an inlay vehicle including a non-woven / barrier fabric a laminated / cut fiberglass laminate constructed and positioned in accordance with the invention. FIGURE 2 is a partial cross-sectional view of the cut glass fiber containing a laminate constructed and placed according to the invention; FIGURE 3 is a schematic view illustrating the process, steps and equipment used in accordance with the invention to manufacture the laminate of FIGURE 2; FIGURE 4 is a partial view of the components of the title of FIGURE 1 showing how the laminate and the additional components are molded; and La FUGURA 5 is an elongated partial sectional view of the title of FIGURE 1 taken along line 5-5. DESCRIPTION OF THE PREFERRED MODALITIES A title 11 constructed and placed in accordance with the invention is shown mounted to the underside of the roof of a motor vehicle 12 in FIGURE 1. The title 11 can be secured in a number of conventional ways at the points 13 well known in the art and not described here. These methods include adhesives, the use of sailboat ties, securing lines and various types of molds. The title 11 can be molded in a non-uniform thickness as shown in FIGURE 2. The title 11 can also include several regions 14 for viewers and a cut region 16 for a dome lamp and an open wide region 17 for a Sunroof on the roof of the vehicle 15. FIGURE 2 illustrates in the detailed cross-section the components of a cut glass fiber containing a laminate 21 constructed and placed in accordance with the invention. The laminate 21 includes a non-interlaced fabric 22, a barrier film 23 and a cut glass fiber layer 24 including a thermoplastic adhesive 26. When assembled, the non-interlaced fabric 22, will be the back surface of the title 11 adjacent to the metal roof of the vehicle. The laminate 21 formed of the non-interlaced fabric 22, the barrier film 23 and the cut fiberglass layer 24 according to the process illustrated in FIGURE 3 will provide significant advantages. This includes a laminate which will impart rigidity properties when used as a component in an automotive grade, eliminates the possible resin run-off during post-lamination molding which sometimes occurs, and has sufficient elasticity properties which allow excellent conformation to the drawing-deep areas when molded. The non-woven fabric 22 used for forming the laminate 21 is formed from a tangled polyester fiber and has a weight between 0.50 to 1.75 oz / yd2 (17-60 g / m2). And it is 100% polyethylene fiber (generally refers to PET). In the exemplified embodiment, the non-woven fabric is 100% entangled polyester fiber weighing 1.00 oz / yd2 (34 g / m2). The polyester fiber used to make the fabric or interlacing 22 is a tangled PET fiber having a fineness of between 1.8-2.2. Using a fiber with this fineness, it assists in providing a non-woven fabric 22 with non-draining properties within the laminate. If not very fine fibers are used they are used to make a non-interlaced fabric of the same weight, there is less area surface coverage in the non-interlaced material. This surface of diminished area will be counted for the length of diameter / fineness of the fiber. Because of this, fibers with a fineness between 1.8 and 2.2 increase the area area resulting in a decrease in the permeability of the non-woven fabric 22. This reduction in permeability prevents the barrier film 23 used in the laminate 21 to run through the non-woven fabric 22 and thus inadvertently joining a molding tool during the thermal formation wherein the tool temperatures are generally above the melting temperature of the barrier film. The non-woven fabric 22 is selected to have an elasticity that is adaptable in both machine and cross directions so that the laminate 21 has the desired elastic properties. Preferably, the non-woven fabric chosen has to be between 30 and 60 percent narrow in both directions, machine and cross. More preferably, the breaking properties exceed between 35 and 45 percent and even more preferably an elasticity. Additionally for 1 break point of the elasticity, the tension force is also important physical property. The non-woven fabric 22 is selected so that the tension force is below 7 to 10 pounds of force in the machine direction and less than 4 to 7 pounds in the cross direction. In the preferred embodiments of the invention, the non-woven fabric 22 has a tension force below 8 pounds of force in the machine direction and below 4 to 5 pounds of force in the transverse or cross direction. In addition to the tensile force, the breaking energy is also an important feature of the non-woven fabric 22. The breaking energy corresponds to the area under a tightly tensioned curve, and therefore represents the strength of the material. Accordingly, if the bankruptcy energy is very high, much energy will be required to fill the deep drawing cavity with the laminate 21 hanging from the title mold and will not be adaptable for the desired end use of the laminate 21. The energy of Breakage of a non-interlacing fabric 22 is preferably below 8 to 12 pounds of an inch in the machine direction and below 4 to 7 pounds of an inch in the cross direction. Both bankruptcy, energy and elasticity properties are determined under a modified version of a Test Method for the Textile Materials Breaking and Elasticity Strength ASTM 5035-95.thirst.

Finally, the non-woven fabric 22 is selected to be able to withstand mold temperatures which are generally in the range of 130 to 140 ° C (270 to 285 ° F). A tangled polyester fabric having the characteristics described above is generally softened at a temperature between 250 and 260 ° C. Because of this, the integrity of the non-woven fabric 2 should not be substantially altered when forming an automotive title with a laminate 21 according to the invention. The barrier film 23 is formed of a film that can be formed by one or more layers. There are a variety of widths of said barrier films available which are adaptable for use with the laminate 21. A particular film chosen will depend on the manufacturer's tool of titles and the molding conditions such as the temperature of the tool and the stay time. Whether a stable high heat film or a stable low heat film is u the thickness of the film should be between 1.0-2.0 mil (0.001-0.002") .Preferably, the thickness of the barrier film 23 should be of about 1.5 thousand (0.0015"). The selected barrier film also has an effect on the elastic properties of the final composite and must be chosen according to the tool conditions and the final composite with the desired strand and the required temperature resistance.

The barrier film 23 can be a polyolefin film or it can be a chemical mixture and can be formed of a single or multi-layered structure. As noted, a wide selection of barrier films is adaptable. Specific examples include the Dow Integral 925 film which is three layers having a heat core layer stable up to about 165 ° C (330 ° F) and having polyethylene adhesive outer layers which are activated by heat at temperatures of between 127 ° C (260 ° F). Alternatively, when a film stable to said high heat is not required, a polyolefin film, such as the Dow Integral 909 or 906 film can be u The trigger point of these films is below the mold temperatures and is activated at temperatures between 100 ° C (212 ° F). In spite of the selected barrier film, the barrier film 23 must have a tension modulus (2% drier) between about 9,000-50,000 pounds / inch2 before lamination. Of course, the choice of the barrier film 23 will have an effect on the final elastic properties of the laminate 21 and should be chosen according to the molding conditions and the desiredly desired laminate 21. In these cases, the tension modules (2% drying) are determined using an ASTM D882 test method. The barrier film 23 according to the invention is non-porous and has a crown surface. This assists in the bonding of the barrier film 23 and the non-woven fabric 22. The treatment of the crown surface helps in achieving a bond between the two layers which play an important role in achieving the desired adjustment properties of the final laminate. 21. The treated corona side of the barrier film 23 is laminated against the non-interlaced fabric 22. The fiberglass layer 24 is formed by depositing the cut glass fiber on the exposurface of the barrier film 23. The fiberglass is applied to provide a range of between 30 and 200 g / m2 of fiberglass with yarns having a length between 1.0 and 4.0 inches. Preferably, the length of the cut interlaced yarns is 2.0 inches. The cut glass fibers are applied to the barrier film in a random fashion and combined with a chemical anti-static agent to reduce the static build-up in the glass cutter. Prior to the completion of the assembly of the laminate 21, a thermoplastic adhesive is applied to the fiberglass cut in a random manner. If a resin powder is uas in the illustrated mode, the particle size used can vary between 100 and 500 microns having an average of between 200 and 300 microns. The adhesive resin is thermoplastic and can be, for example polyethylene, polyester polymer vinyl acetate. Generally, the amount of thermoplastic adhesive applied depends on the amount of glass fiber deposited on the barrier film 23. FIGURE 3 illustrates the steps of the process and an apparatus 31 used to manufacture the laminate 21. Here the non-woven fabric 22 is wrapped in a roll of fabric 32 in a harness 33 (Station 1) is fed with the rough side down is fed under a position of the film 34. The position of the film 34 includes a first roll 36 and a second roll 37 (Station 2). In the embodiment illustrated in FIGURE 3, one or both rolls 37 and 38 can be used to feed the barrier film 23. The two rolls allow a continuous feed when a roll is empty, or to feed multi-barrier films. layers for forming laminate 21. The barrier film 23 is fed over a three-roll holding station (Station 3) and the non-interlaced fabric 22 is fed under the holding rolls 38. The non-interlaced fabric 22 and the barrier film 23 are fed between a second pair of clamping rollers 39 (Station 3) to form a loose composite of non-interlaced barrier film / fabric 27. Compound 27 is fed below a dispenser of cut fiberglass 41 ( Station 4) wherein the fiberglass cut in the desired amount is deposited on the exposed surface of the barrier film 23. The compound 27 is then fed under a hopper of resin dispenser 42 (Station 5) which deposits the desired amount of thermoplastic adhesive 26 onto the cut fiberglass layer 24 in the barrier film 23. When the barrier film 23 passes through a second pair of rollers 39, is positioned so that the treated corona surface will be laminated facing the non-interlaced fabric 22. The non-interlaced fabric 22 is typically has a characteristic flat and smooth side this due to the bonding and interlacing technology used in the manufacturing. According to the invention, the method of forming laminate 21 includes placing the non-interlaced fabric 22 into a harness so that the smooth or flat surface is bonded with the barrier film 23. According to this, in FIGURE 3 the lower surface of the non-interlaced fabric 22 is the rough surface. It has been found that this arrangement imparts reduced grinding properties in the final title which are advantageous for the molding of the title. The resin / fiberglass / barrier / non-interlacing film composite 27 is then fed through or furnace 3 (Station 6) where the adhesive powder 26 and the barrier film 23 are activated by heat. The furnace 43 can be for any adaptive type, but configured so that heat is applied to the compound 27. In the preferred embodiment illustrated in FIGURE 3, the furnace 43 includes a number of electric infrared heating elements 44 which are located on top-side of the furnace 43 to apply the heat to the side of the glass fiber of compound 27 only. There is no direct heating being applied from the bottom to the non-interlaced fabric 22 of compound 27. The furnace is monitored by measuring the temperature of compound 27 as it exists in furnace 43. Depending on the particular barrier film, the fiber of Glass and the resin used, the oven temperature is monitored so that a bond is achieved between the non-woven fabric 22 and the barrier film 23. At the same time, the thermoplastic adhesive 26 melts and mixes within the fiber of cut glass falling into the barrier film 23. If the operating temperature of the furnace 43 exceeds the desired temperature, the barrier film will be activated and also strongly bonded to the non-interlaced fabric 22 thereby putting at risk the deep drawing and the high narrow properties of the finished laminate 21. The primary objective is to provide sufficient bond between the barrier film 23 and the non-woven fabric 22 so that the delamination does not occur before the compound 27 is molded by the title maker. After a thermoplastic adhesive 26 has been activated in the furnace 43 the composite 27 is laminated to a first clamping roller 45 (Station 7) to form the laminate 21. The first clamping roller station 45 is maintained at a temperature just below room temperature and apply a downward pressure of between 10 and 80 pounds / in2 to compound 27. Preferably, between 30 and 40 pounds / inch2 of pressure is applied, and most preferably it is between 20 pounds / inch2 to form the laminate 21. The actual pressure depends on the amount of glass fiber added in the fiberglass cutter 41 and the thickness deposited in the barrier film 23 If a lot of pressure is applied to a first fastening station 45 and the temperature of the furnace 43 exceeds the activation temperature of the barrier film 23, the pressure of the clamping roll will force the glass fiber into the barrier film 23 and will cause perforation ones there. If this occurs, the non-drip properties through the barrier film 23 will be lost. The use of a cold hold roll in the first hold roll station 45 rapidly solidifies the thermoplastic adhesive 26 where the lamination occurs. . The laminate 21 is then subsequently cooled in a cooling station 46. The cooling station 46 includes a first cooling roller 47 and a second cooling roller 48. The laminate 21 passes over the first cooling roller 4? and below the second cooling roller 48. Both rollers 47 and 48 are maintained below room temperature. The cooling rollers subsequently cool the laminate 21 and provide a desirable amount of tension between the cooling station 46 and a final make-up roller 49 where the laminate 21 is cut (Station 9) EXAMPLE 1 A laminate formed using the apparatus and the process described in connection with FIGURE 3 was evaluated. The evaluation was carried out by preparing a 1% water solution test with a nonionic weight of a wet agent and 1% by weight of any bleach. The mixture includes the bleach to provide a simple visual evaluation of the runoff properties. A sample of a finished laminate 21 is obtained in the final make-up roll 49. The test solution is then spread on the cut glass fiber on the side of the laminate 21 using a piece of sponge. After allowing the solution to stand in the laminate 21 for one minute, the laminate 21 is turned over to determine whether the solution drained through the layers. The laminate 21 should have no sign that the solution drained through the non-interlaced side of the fabric.

A positive test, or appearance of the decolorizer on the non-interlaced fabric 22 would indicate that there are holes produced in the barrier film 23 during the rolling process. The finished laminate 21 was then tested for physical testing on a tension testing machine with an Instron 4400 series tester. A total of at least 5 samples were cut in the machine direction and in the transverse direction. The samples were then bleached and cut in 1"x 6" specimen side with the length of 6"direction being tested.This is a modified version of the Test Method for the Strength of Rupture and Elasticity of Textile Materials ASTM D 5035 -95 An initial jaw space of 1"over the length of the cut fiberglass is used. If a 2"fiberglass composite is produced the initial drawing space should be 3". This is to ensure that the cut fiberglass yarns will not be present in both the upper and lower test jaws because this tends to cause inaccurate elasticity results. The test speed was 12yds / rnin. The final elasticity at the point of failure, no final elastic load, in both machine and transverse directions of the final laminate exceeded between 30 and 40%. The bankruptcy energy has been calculated to be less than 20 pounds / inches. (This is not calculated on the total load, but at the breaking point of the laminate.

EXAMPLE 2 The manufacture of a title shown in FIGURE 5 having an outer layer of a decorative vinyl or fabric 23 reinforced with a thin foam to mask irregularities of the surface is adhered to the outer surface of a foam core 29 impregnated with a liquid resin as is isocyanide as is well known in the art, and a second layer of glass fibers between them. The components are attached in the manner described above and placed inside a mold 51 and closed as shown in FIGURE 4. The mold 51 is heated to a temperature between 93 ° and 177 ° C (200 ° to 350 ° F) from one to ten minutes and thermoplastic resins attach to the layers. In the removal and cooling of the mold compound, the various layers are sufficiently adhered to one another so that the part can be used as a title by absorbing a sound in a motor vehicle. An alternative method involves pre-heating the compound to adhere several layers and give the figure to the final part using a cold mold. By providing a non-interlaced fabric / barrier / fiberglass film network cut according to the invention, several advantages for the construction of automotive titles are obtained. The use of a finer fiber of union having a density in a range of 1.8 to 2.2 results in a compound having an elasticity of bankruptcy exceeding 30 to 40% in both directions, mechanical and transverse. The energy breaking point is less than 20 pounds / inch in both directions. The improved elastic properties combined with the low energy of bankruptcy, they allow the deep drawing to be obtained in addition to the absence of holes in the barrier film preventing runoff through the barrier film or resin. It will be due to this being seen that the objects placed above, on those apparent of the previous description, are efficiently addressed and because certain changes can be made by carrying out the method described above in the article without departing from the spirit and vision of the invention, it is intended that any case contained in the description above and shown in The accompanying drawings should be interpreted as illustrative and not in a limiting sense. It should also be understood that the following clauses are intended to cover all the generic and specific features of the invention described herein and all the statements of the invention's vision which, in language manner, could be mentioned to fit between them.
