BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous fiber-reinforced thermoplastic resin molding material composed of a woven fabric made of reinforcing continuous fibers and thermoplastic resin fibers.

0002

[Prior Art] Conventionally, as a molding material for making a continuous fiber-reinforced thermoplastic resin molded article, continuous reinforcing fibers are aligned and immersed in a molten thermoplastic resin to inject resin into the reinforcing continuous fibers. Sheet-like materials made by impregnating resin and then cooling and solidifying the resin are known. However, this molding material is extremely hard at room temperature and has poor drape properties (mold conformability) if left as is, so when molding it, it must be heated in an oven to make it flexible and then pressurized with a press. However, when the molded article is required to have a delicate shape, it is extremely difficult to handle it. Furthermore, when using a thermoplastic resin with a high melting point such as polyetheretherketone, the thermoplastic resin is melted in an inert gas atmosphere to prevent oxidation when impregnating the reinforcing continuous fibers with the thermoplastic resin. Care must be taken to immerse the continuous fibers in the shiso, which increases the size of the equipment.
There were also problems such as high costs.

[0003] In order to deal with this, thermoplastic resin is made into fibers and this is woven together with reinforcing continuous fibers to obtain a mixed woven fabric, or the two are mixed in some way at the yarn stage. A method is known in which a blended fabric obtained by weaving is used as a molding material (fiber matrix method). The fabric used in such a fiber matrix method has the advantage of good drapability because it is flexible.

0004

[Problems to be Solved by the Invention] However, the fabrics used in the fiber matrix method are woven with almost untwisted fiber yarns as the warp and weft to form a coarse weave, so they are not flexible. It has poor cutting properties, and the fibers fray when cutting.
There was a problem that workability was extremely poor. In addition, when the woven fabric is set in a mold for molding, it tends to bend, and as a result, the reinforcing fibers in the molded article are bent, resulting in problems such as poor appearance and poor reinforcing effect.

The present invention has been made in view of such conventional problems, and provides a continuous fiber-reinforced thermoplastic fabric made of a fabric that has good drapability, can be easily cut without fraying when cut, and is less prone to bending. The purpose is to provide resin molding materials.

[0006]

[Means for Solving the Problems] As a result of intensive studies to solve the above-mentioned problems, the present inventors have devised a thermoplastic resin by heating and pressurizing a fabric made of reinforcing continuous fibers and thermoplastic resin fibers. Resin fibers can be thermally bonded to the threads that cross them, or warp or weft threads containing thermoplastic resin fibers can be made into a ribbon shape and the threads that cross them can be bonded or impregnated. The present invention was completed based on the discovery that it is possible to prevent fibers from fraying and bending when set in a mold.

That is, the first invention of the present application is composed of a woven fabric made of reinforcing continuous fibers and thermoplastic resin fibers, and the thermoplastic resin fibers in the woven fabric are thermally bonded to the threads intersecting with the woven fabric. The subject matter is a continuous fiber-reinforced thermoplastic resin molding material characterized by:

Further, the second invention of the present application is composed of a woven fabric made of reinforcing continuous fibers and thermoplastic resin fibers, and the threads containing the thermoplastic resin fibers in the woven fabric are thermally melted into a ribbon shape and intersected with the woven fabric. The gist of the invention is a continuous fiber-reinforced thermoplastic resin molding material, which is characterized by being adhesively bonded to or impregnated with fibers.

The present invention will be explained in detail below. The woven fabric used in the present invention may be made of reinforcing continuous fibers and thermoplastic resin fibers, and the arrangement of the fibers within the woven fabric is not particularly limited. That is, the woven fabrics used in the present invention can be broadly classified into woven fabrics for unidirectional reinforced molded bodies in which reinforcing continuous fibers are arranged only in either the warp or the weft, and , bidirectional reinforced fabrics for molded bodies in which reinforcing continuous fibers are arranged in both the warp and the weft. Furthermore, within these fabrics, the reinforcing continuous fibers and the thermoplastic resin fibers may each constitute separate threads and be used as warp and/or weft threads, or the reinforcing continuous fibers and the thermoplastic resin fibers may be used as warp and/or weft threads. It is also possible to mix the fibers with resin fibers to form a single thread and use it as the warp and/or warp thread. Typical examples of textiles that can be used in the present invention are listed below and are schematically shown in FIGS. 3 and 4.

(1) Unidirectional reinforced fabric for forming (see Figure 3) (a) As shown in Figure 3(a), either the warp or the weft is replaced with a yarn consisting only of reinforcing continuous fibers (reinforcing A mixed woven fabric in which one yarn (referred to as a continuous fiber yarn) and the other yarn (referred to as a thermoplastic resin fiber yarn) 2 are made of only thermoplastic resin fibers. In this case, it is preferable to use the reinforcing continuous fiber yarn 1 as the warp. (b) As shown in FIG. 3(b), a mixed woven fabric in which one of the warp and weft is a reinforcing continuous fiber yarn 1 and a thermoplastic resin fiber yarn 2, and the other is a thermoplastic resin fiber yarn 2. In this case as well, it is preferable to use the reinforcing continuous fiber yarn as the warp yarn. In addition, in the drawing, the same number of reinforcing continuous fiber yarns 1 and thermoplastic resin fiber yarns 2 arranged in parallel are used,
Although they are arranged alternately, the ratio of the number used, arrangement, etc. can be changed as appropriate.

(e) As shown in Figure 4(e), both warp and weft threads are
A blended fabric with 3 mixed yarns.

The weave structure of the fabric used in the present invention is usually the plain weave shown in FIGS. 3 and 4, but is not limited to this, and other weave structures such as diagonal weave, satin weave, and nanako weave are also used. Weaving or the like may also be used. In addition, when arranging reinforcing continuous fibers in both the warp and weft directions, Japanese Patent Application Laid-Open No. 64-4
As shown in Japanese Patent Application No. 5841 (Japanese Patent Application No. 62-200905), it is preferable to have a woven structure in which the woven structure is composed only of reinforcing continuous fibers even after the thermoplastic resin fibers are melted.

The reinforcing continuous fibers used in the present invention are not particularly limited as long as they have a higher melting point than the thermoplastic resin fiber yarn used, such as glass fibers, carbon fibers, aramid fibers, alumina fibers, metal fibers, etc. Not done. When glass fiber is used as the reinforcing continuous fiber and a thread consisting of a large number of bundled glass fibers is used as the warp or weft, the diameter of the monofilament is usually 3 to 23 μm, preferably 5 to 15 μm, The number of convergence is preferably 100 to 800.

Thermoplastic resin fibers used in the present invention include polypropylene, polyethylene, polyamide, polyester, polycarbonate, polyacetal, polysulfone, polyethersulfone, polyetheretherketone, polyetherketone, polyetherimide, polyphenylene sulfide, etc. It is not particularly limited as long as it can be made into a fibrous form. The fibers may be in the form of bundles of long fibers or staple yarns. The monofilament diameter is usually 10-2
00 μm, preferably 40 to 80 μm.

The ratio of reinforcing continuous fibers and thermoplastic resin fibers in the woven fabric used in the present invention is determined by taking into account the reinforcing material content in the molded article produced thereby. The fiber volume content is usually 3
It is selected to be 0 to 65%, preferably 45 to 60%.

[0016] The molding material according to the first invention of the present application is obtained by thermally bonding the thermoplastic resin fibers to the intersecting threads of the above-mentioned woven fabric consisting of reinforcing continuous fibers and thermoplastic resin fibers. It is characterized by For example, Figure 3
In the fabric shown in FIG. 4, a thermoplastic resin fiber yarn 2 and a mixed yarn 3 containing thermoplastic resin fiber are combined with other yarns (reinforcing continuous fiber yarn 1, thermoplastic resin fiber yarn 2, mixed yarn 3) that intersect therewith. ) is thermally bonded to the This thermal adhesion of thermoplastic resin fibers is obtained by subjecting the fabric to heating and pressure processing. As shown in FIG. 5, the heating and pressure processing of the textile fabric involves pressing the textile fabric 5 against a heating roll 6 whose surface temperature is raised to a predetermined temperature with an appropriate pressure. These rolls 6,
It is preferable to adopt a heating and pressurizing method according to step 7. In the method using such a hot roll, it is possible to carry out a continuous process in which the fabric 5 is unwound from the raw fabric 8, passed between the hot roll 6 and the presser roll 7, and then wound up as a take-up roll 9. This is possible, and by controlling the surface temperature of the heat roll 6, the heating temperature of the thermoplastic resin fibers of the fabric can be controlled, and the advantage is that temperature control becomes easy. Note that a metal roll is usually used as the heat roll 6 used for heating and pressing the fabric, and a rubber roll is used as the presser roll 7, but if necessary, a metal roll can also be used as the presser roll 7, and it can also be heated. You may also do so. Further, in FIG. 5, the fabric 5 is run linearly between the heat roll 6 and the presser roll 7, but if necessary, the fabric 5 may be brought into contact with the outer peripheral surface of the heat roll 6 at an appropriate angle to preheat it. Alternatively, another heating roll may be placed upstream of the heating roll 6 to preheat the fabric.

The heating temperature for thermally adhering the thermoplastic resin fibers in the fabric to the threads crossing them is usually below the melting point of the thermoplastic resin fiber threads and above the glass transition point. When the woven fabric is heated and pressurized at this temperature, the resin fibers in the woven fabric do not completely melt, but they develop viscosity, and as a result, the resin fibers thermally bond to adjacent fibers while retaining their fiber form. Furthermore, it is also thermally bonded to the fibers of the threads that intersect with it.

When carrying out the above-mentioned heating and pressing process, if the fabric used is a fabric for a unidirectional reinforced molded article, reinforcing continuous fibers are arranged in the warp direction of the fabric, and as shown in FIG.
As shown in FIG. 2, when processing with the hot roll 6, it is preferable to apply a large tension in the warp direction of the fabric (travel direction of the fabric) and uniformly in the width direction. When heat and pressure processing is performed while applying tension in this manner, the warp yarns containing reinforcing continuous fibers in the obtained molding material are elongated and become relatively flat. For example, in Fig. 1, reinforcing continuous fiber yarn 1 is inserted into the warp.
It shows a molding material 10 obtained by subjecting a woven fabric using thermoplastic resin fiber threads 2 as wefts to heat and pressure treatment while applying tension in the warp direction, (a) is a plan view thereof, (b) ,(
c) is a BB arrow view and a CC arrow view of (a), respectively. As shown in (b) and (c), since the reinforcing continuous fiber yarn 1, which is the warp yarn, is stretched, the curve formed at the intersection with the thermoplastic resin fiber yarn 2, which is the weft yarn, is stretched and stretched. Therefore, the reinforcing continuous fiber yarn 1 is in a substantially linearly extended state, and the thermoplastic resin fiber yarn 2
Only the edges are curved. In the molding material 10 having this configuration, since the reinforcing continuous fiber yarn does not have any curvature, when the thermoplastic resin fiber yarn 2 is melted during molding, the reinforcing continuous fiber yarn sag and bends. Therefore, the appearance of the obtained molded product is good. Note that the stretching of the warp yarns causes a large curvature in the weft yarns, but since the weft yarns are melted during molding, there is no problem at all. In the case of a fabric for bidirectional reinforcing molded articles containing reinforcing continuous fibers in both the warp and weft, pulling the warp with tension will increase the curvature of the reinforcing continuous fibers in the weft, which is undesirable. In this case, there is no need to apply strong tension to the fabric during heating and pressure processing of the fabric.

[0019] The molding material according to the second invention of the present application is a fabric made of the above-mentioned reinforcing continuous fibers and thermoplastic resin fibers. It is characterized by being bonded to or impregnated with the yarn. This molding material, like the molding material according to the first invention of the present application described above, can also be obtained by subjecting a textile to a heating and pressurizing treatment. however,
In this case, the heating temperature of the woven fabric is set to be higher than the melting point of the thermoplastic resin fibers within the woven fabric. When heated and pressurized at this temperature, the resin fibers in the fabric melt, and the thermoplastic resin fiber yarns or mixed yarns constituting one warp or weft become ribbon-like (
(film-like) and adheres to or impregnates the threads that intersect with it. For example, in the fabrics shown in FIGS. 3 and 4, thermoplastic resin fiber threads 2 and mixed threads 3 containing thermoplastic resin fibers are thermally melted into a ribbon shape, and thermoplastic resin fiber threads 2 and mixed threads 3 intersect therewith. (These are also ribbon-shaped) and impregnated into the reinforcing continuous fiber yarn 1. At this time, the degree of impregnation may be such that the ribbon-shaped resin impregnates only one side of the reinforcing continuous fiber yarn and does not reach the opposite side, or may reach the opposite side. The degree of these impregnations can be adjusted by controlling heating temperature, heating time, pressing force, and other conditions.

Even in the process of heat-melting yarn containing thermoplastic resin fibers into a ribbon shape, if the fabric used is a fabric for a unidirectional reinforced molded article, the reinforcing continuous fibers are arranged in the warp direction of the fabric. However, it is preferable to apply a large tension in the warp direction. Figure 2 shows reinforcing continuous fiber yarn 1 in the warp.
It shows a molding material 11 obtained by subjecting a woven fabric using thermoplastic resin fiber threads 2 as wefts to heat and pressure treatment while applying tension in the warp direction, (a) is a plan view thereof, (b) ,(
c) is a BB arrow view and a CC arrow view of (a), respectively. As shown in (b) and (c), the reinforcing continuous fiber yarn 1, which is the warp, is stretched almost linearly,
The upper and lower surfaces thereof are partially impregnated with a thermoplastic resin fiber thread 2 which has been thermally melted into a ribbon shape. This molding material 11
Similarly to the molding material 10 shown in FIG. 1, it is possible to produce a molded product with a good appearance in which the reinforcing continuous fiber yarns in the molded product are not bent. Note that although the ribbon-shaped thermoplastic resin fiber yarns 2 are shown separated from each other in FIG. 2, this is for the purpose of explanation; Adjacent ribbons may adhere to each other slightly due to crushing, but there is no particular problem.

[0021]

[Operation] The molding material of the first invention of the present application is a woven fabric consisting of reinforcing continuous fibers and thermoplastic resin fibers, in which the thermoplastic resin fibers are thermally bonded to the threads crossing them. The reinforcing continuous fibers contained in the woven fabric are fixed using thermoplastic resin fibers as a binder, so that no fraying occurs during cutting, and cutting is easy. Furthermore, when molding using this material, bending of the mesh does not occur. Furthermore, since the thermoplastic resin fibers are not completely melted and therefore maintain their fiber form, they are flexible and maintain good drape properties. Therefore, it can be applied to complex shapes and products with good appearance can be obtained.

[0022] In addition, the molding material of the second invention of the present application is a woven fabric consisting of reinforcing continuous fibers and thermoplastic resin fibers, in which the threads containing the thermoplastic resin fibers are formed into a ribbon shape, and the intersecting threads are formed into a ribbon shape. On the other hand, since the reinforcing continuous fibers are bonded or impregnated, the reinforcing continuous fibers are fixed using the thermoplastic resin ribbon as a binder, so that no fraying occurs during cutting, and cutting is easy. Moreover, when molding using this material, no bending of the mesh occurs. Note that the threads containing thermoplastic resin fibers are melted into a ribbon shape, and the intersecting threads are impregnated, so the flexibility is lower than the original fabric, but the threads containing thermoplastic resin fibers are made into ribbons. The thermoplastic resin fibers in the fabric are not melted to form a single sheet, so it maintains flexibility, has good drapability, and has a complex shape. It can be applied to any shape, and it is possible to obtain a product with a good appearance. Furthermore, in this molding material, since the thermoplastic resin is partially impregnated between the reinforcing continuous fibers, the impregnation speed during molding is fast, and the molding cycle can be shortened.

Effects of the Invention As explained above, the continuous fiber-reinforced thermoplastic resin molding material of the first invention of the present application can be used in fabrics made of reinforcing continuous fibers and thermoplastic resin fibers. Since it is characterized by being thermally bonded to the intersecting threads, the reinforcing continuous fibers are bound within the molding material using thermoplastic resin fibers as a binder, which prevents them from fraying when cut. In addition, thermoplastic resin fibers retain their fiber form and have appropriate flexibility, resulting in good drapability. It has the advantage that the molding operation is easy, it can be applied to molding of complicated shapes, and the appearance of the obtained molded product is good.
