Definitions
- the present invention relates to a method for producing composite parts with a thermoplastic polyamide and reinforcing agents embedded therein.
- thermoplastic polymer usually in powder form, is brought into contact with the reinforcing agents and then melted, so that the reinforcing agents are wetted with the polymer material. After the polymer melt has cooled and solidified, the reinforcing agents are embedded in the polymer material.
- Polymers such as e.g. Polyether sulfone, polypropylene, polyphenylene sulfide or polyamides.
- the object of the invention is to provide a method for producing composite parts with a thermoplastic polyamide and reinforcing agents embedded therein, in which the above-mentioned problems are avoided and high-quality composite parts with application temperatures above 180 ° C. can also be produced.
- the reinforcing agents are brought into contact with a pre-condensate (prepolymer) of the polyamide which has a lower molecular weight and therefore a lower melt viscosity than the polyamide and that the pre-condensate in contact with the reinforcing agents exceeds its melting point is heated so far and for so long that the resulting melt can wet the reinforcing agents and at the same time condense to the polyamide.
- pre-condensate prepolymer
- the precondensate can wet the reinforcing agents much better and more uniformly than is the case with the fully condensed, high molecular weight polymer. The latter arises only after and / or simultaneously with the wetting of the reinforcing agents in contact with them. With a suitable choice of the pre-condensate it can be achieved that when it melts it is almost as liquid as water and spontaneously wets the reinforcing agent. The then drastically increasing viscosity within possibly only a few seconds then no longer has a detrimental influence on the wetting of the reinforcing agents.
- thermosensitive reinforcing agents such as natural fibers
- the precondensate used is preferably one having a molecular weight in the range from 600 to 3000 g / mol.
- Pre-condensates that can be used are those that are partly aromatic, but also completely composed of aliphatic units. Mixtures of partially aromatic precondensates with aliphatic precondensates are also possible.
- partially aromatic precondensates those based on terephthalic acid, isophthalic acid or their mixtures or blends are particularly suitable.
- aliphatic precondensates there are in particular those which are straight-chain or branched-chain aliphatic or cycloaliphatic dicarboxylic acid having 6 to 36 carbon atoms such as adipic acid, suberic acid, azelaic acid, sebacic acid, dodecanedioic acid, brassylic acid, trimethyl adipic acid, ice and / or trans-cyclohexane -1, 4- dicarboxylic acids, ice and / or trans-cyclohexane-1,3-dicarboxylic acid and dimethyl fatty acids are derived.
- adipic acid suberic acid, azelaic acid, sebacic acid, dodecanedioic acid, brassylic acid, trimethyl adipic acid, ice and / or trans-cyclohexane -1
- Suitable straight-chain or branched-chain aliphatic diamines for the preparation of suitable aliphatic precondensates are those having 4 to 13 carbon atoms, such as hexamethylenediamine (1, 6-diaminohexane), 1, 8-diamino-octaone, 1, 10-diaminodecane, 1, 12-diaminododecane, 1, 4-diaminobutane, 2,2-dimethyl-1, 3-diaminopropane, 2,2,4-and / or 2,4,4-trimethyl-1, 6-diaminohexane , 2-methyl-1, 5-diaminopentane, 5-methyl-1, 9-diaminononane.
- Suitable cycloaliphatic diamines for the preparation of the precondensates are those having 6-26 carbon atoms, such as ice and / or trans-1,4-diaminocyclohexane, ice or trans-1,3-diaminocyclohexane, ice or trans-1,4- Bis (aminomethyl) cyclohexane, ice or trans-1,3-bis (aminomethyl) cyclohexane, 3 (4), 8 (9) -bis (aminomethyl) tricyclo- [5.2.2.0 2 6 ] -decane, 2 ( 3), 5 (6) - bis (aminomethyl) norbornane, 1, 8-diamino-p-menthan, 3-amino-3,5,5'-trimethylcyclohexylamine, bis- (4-amino-3-methylcyclohexyl) methane, and bis-2,2- (4-aminocyclohexyl) propane.
- Suitable lactams or ⁇ -aminocarboxylic acids for the production of suitable aliphatic precondensates are those having 6 to 12 carbon atoms, such as caprolactam, lau nlactam or ⁇ -aminocaproic acid, ⁇ -aminolauic acid and ⁇ -aminoundecanoic acid, and ⁇ -aminononanoic acid.
- Suitable aliphatic diamines for the production of suitable aliphatic precondensates are those with 8-26 carbon atoms.
- mixtures or blends of the above-mentioned building blocks including mixtures or blends of partially aromatic with other partially aromatic, partially aromatic with aliphatic and aliphatic with other aliphatic polyamides, are also suitable.
- polyamide compositions can be produced which can be assigned to the types homopolyamides, copolyamides, block copolyamides, their blends or their alloys.
- Homopolyamides are formed, for example, by using precondensates of types PA 46, PA 66, PA 610, PA 1010, PA 612, PA 912, PA 1212, PA 6, PA 11 and PA 12, and also by using precondensates based on cyclic Diamines / dicarboxylic acids or alkyl-substituted cyclic diamines / dicarboxylic acids.
- Copolyamides or block copolyamides are formed when using precondensates of types PA 46/6, PA 46/1 1, PA 46/12, PA 46/66, PA 46/6/66, PA 46/69, PA46 / 611, PA 46 / 612, PA 46/1212, PA 6/66, PA 11/66 or PA 12/66, and also of pre-condensates of the type PA 46 with aliphatic cyclic diamines / dicarboxylic acids or corresponding aliphatic alkyl-substituted cyclic diamines / dicarboxylic acids.
- thermoplastic polyamide the precondensate of which is used
- the melting point and other specific properties such as elasticity, resistance to hydrolysis or impact resistance can be varied within a wide range by selecting and possibly combining different precondensates of the type mentioned.
- additives such as heat or UV stabilizers, antioxidants or impact modifiers, etc. can of course also be used in the context of the invention in a conventional manner.
- Reinforcing fibers in particular carbon fibers, glass fibers, aramid fibers, natural fibers (such as hemp, flax, jute, ramie, cotton fibers) or metal fibers, in the form of single fibers, semi-finished textile products, fabrics or tapes, can be used as reinforcing agents.
- non-fibrous reinforcing or filling materials in particular mineral (e.g. layered silicates) and / or metallic and / or magnetic and / or magnetizable substances, can also be used as reinforcing agents.
- the precondensate can be brought into contact with the reinforcing agents by methods known per se, such as:
- Powder impregnation fluidized bed, or electrostatic, or flame spraying, or scatter coating process
- the processes can be carried out continuously or batchwise.
- the process according to the invention results in application products such as, for example, glass or carbon fiber-reinforced reinforcement tapes for crude oil and natural gas production pipes and lines (for example off-shore), reinforcements for buildings and bridges or partial reinforcements for injection molded parts, with composite parts being inserted into an injection mold and subsequently overmolded.
- the method according to the invention can also be used to produce flat, fiber-reinforced semi-finished products, which can be thermoformed (such as deep drawing, pressing, etc.) to form three-dimensional components in a subsequent step (e.g. structural components in automotive engineering).
- the precondensation in contact with the reinforcing agent is essentially already in the final form of the product or semi-finished product to be produced. This applies in particular when using high-melting polyamides.
- the parts resulting from the process according to the invention are thermoplastic, they can in principle also be thermoformed at least to a certain extent in a subsequent step.
- the HT2 pre-condensate powder Grivory XE 3774 VK produced by EMS-Chemie AG with a relative viscosity of 1.17 (measured as 0.5% m-cresol solution) is evenly sprinkled on a carbon fiber fabric.
- the melting point of this pre-condensate is 275 ° C (DSC, 1st heating, 80 min).
- the carbon fiber fabric is an atlas fabric made of 12K rovings of the type Tenax 5N21 with a basis weight of 440 g / sqm. A weight ratio of 30% precondensate powder to 70% carbon fiber fabric is set.
- the tissue thus prepared is placed in a flat steel plate tool preheated to 320 ° C.
- the cavity is blanketed with nitrogen before the tool is closed.
- the tool is closed and the prepared tissue is pressed at a pressure of 5 bar for 3 minutes.
- the composite part produced in this way is characterized by complete impregnation of the fibers.
- the melting point of the resulting polymer is 307 ° C.
- a powdered PA 46 precondensate powder is sprinkled evenly on a carbon fiber fabric.
- the melting point of this precondensate is 290 ° C (DSC, 1st heating, 807mi ⁇ ).
- the carbon fiber fabric is a 4/1 atlas fabric made of 12K rovings of the type Tenax 5N21 with a basis weight of 440 g / sqm.
- a weight ratio of 30% precondensate powder to 70% carbon fiber fabric is set.
- the tissue thus prepared is placed in a flat steel plate tool preheated to 300 ° C.
- the cavity is blanketed with nitrogen before the tool is closed.
- the tool is closed and the prepared tissue is pressed at a pressure of 5 bar for 3 minutes.
- the impregnated and post-condensed plate is removed.
- the composite part produced in this way is characterized by complete impregnation of the fibers.
- the melting point of the resulting polymer is 290 ° C.
- a 1: 1 mixture of powdered PA 46 pre-condensate (from example 2) and PA 6T / 66 pre-condensate (from example 1) is sprinkled evenly onto a carbon fiber fabric (from example 1).
- a weight ratio of 30% precondensate powder to 70% carbon fiber fabric is set.
- the tissue thus prepared is placed in a flat steel plate tool preheated to 320 ° C.
- the cavity is blanketed with nitrogen before the tool is closed.
- the tool is closed and the prepared tissue is pressed at a pressure of 5 bar for 3 minutes.
- the impregnated and post-condensed plate is removed.
- the composite part produced in this way is characterized by complete impregnation of the fibers.
- the melting point of the resulting polymer is 246 ° C and is therefore below the melting point of the two pre-condensate components used.
- a layer of a reinforcement textile a 4/1 atlas fabric made of 12K carbon fiber rovings of the type Tenax 5N21 with a basis weight of 440 g / sqm, is drawn off.
- powdered PA 6T / 66 precondensate (from Example 1) with a relative viscosity of 1.17 (measured as a 0.5% m-cresol solution) is uniformly applied to the reinforcing textile.
- the amount of powder is adjusted via the speed of a needle roller so that a weight ratio of 30% precondensate powder to 70% carbon fiber fabric is achieved.
- the reinforcement textile prepared in this way then passes through an infrared heating zone covered with nitrogen, at the end of which the material reaches a temperature of 320 ° C.
- the reinforcing textile with the now liquid pre-condensate is then fed into a double belt press in which the laminate is pressed at a temperature of 320 ° C and a pressure of 5 bar and at the same time post-condensed.
- the laminate is then cooled to 250 ° C under a pressure of 5 bar.
- the composite material produced in this way is characterized by a complete impregnation of the fibers. Either it is cut into sheets using a cutting device or wound up.
- the melting point of the resulting matrix polymer is 307 ° C.
- Example 5 Solid phase post-condensation of composite parts with PA 6T / 66 pre-condensate
- a composite part produced according to Example 1 with a relative viscosity of 1.16 (measured as a 0.5% m-cresol solution) is stored in an oven under a nitrogen atmosphere at 300 ° C. for 1 hour.
- the solid phase post-condensation that occurs here increases the molecular weight and, in conjunction with this, the viscosity in such a way that the strength of the composite part increases considerably. It was no longer possible to determine the relative viscosity in m-cresol because the sample could no longer be dissolved.
