Abstract:
The invention relates to a composition for thermoplastic composite material comprising: 30% to 60% by volume, preferentially 35% to 50% by volume, of a thermoplastic matrix comprising from 50% to 100% by weight of a semi-crystalline polyamide polymer and from 0% to 50% by weight of at least one additive and/or of at least one other polymer, 40% to 70% by volume, preferentially 50% to 65% by volume, of long reinforcing fibers (or of long fibrous reinforcement), said thermoplastic matrix impregnating said long reinforcing fibers (or said long fibrous reinforcement), said semi-crystalline polyamide polymer being:      a) a reactive composition comprising or consisting of at least one reactive polyamide prepolymer which is a precursor of said semi-crystalline polyamide polymer, or, as an alternative to a), b) a nonreactive composition of at least one polyamide polymer, said composition being that of said thermoplastic matrix defined above,       and said reactive polyamide prepolymer of the composition a) and said polyamide polymer of the composition b) comprising or consisting of at least one BACT/XT copolyamide.

Claim (Index 1):
A composition suitable for a thermoplastic composite material, comprising:\n 30% to 60% by volume of a thermoplastic matrix comprising from 50% to 100% by weight of a semi-crystalline polyamide polymer and from 0% to 50% by weight of at least one additive and/or of at least one other polymer, 40% to 70% by volume of long reinforcing fibers, wherein\n said thermoplastic matrix impregnates said long reinforcing fibers, \n said semi-crystalline polyamide polymer comprises at least one BACT/XT copolyamide in which: \n BACT is a unit comprising an amide unit present at a molar content ranging from 20% to 70%, wherein BAC is chosen from 1,3-bis(aminomethyl)cyclohexyl (1,3-BAC), 1,4-bis(aminomethyl)cyclohexyl (1,4-BAC) and a mixture thereof, and wherein T is terephthalic acid, \n XT is a unit comprising an amide unit present at a molar content ranging from 30% to 80%, wherein X is a C9 to C18 linear aliphatic diamine, and wherein T is terephthalic acid, \n in the BACT and/or XT units, independently of one another, up to 30 mol %, relative to the total amount of dicarboxylic acids, of the terephthalic acid can be replaced with other aromatic, aliphatic or cycloaliphatic dicarboxylic acids comprising 6 to 36 carbon atoms and \n in the BACT and/or XT units, independently of one another, up to 30 mol %, of the BAC and/or where appropriate of X, relative to the total amount of diamines, can be replaced with other diamines comprising from 4 to 36 carbon atoms and \n in the copolyamide, no more than 30 mol %, relative to the total amount of monomers, can be formed by lactams or aminocarboxylic acids, and \n on condition that the sum of the monomers which replace the terephthalic acid, the BAC and X does not exceed a concentration of 30 mol %, relative to the total amount of monomers used in the copolyamide, and \n on condition that BACT and XT units are always present in said polyamide polymer.
