Abstract (en)
[origin: WO2015159020A1] The invention relates to a moulding composition, in particular for a thermoplastic composite material, including at least one semi-crystalline polyamide obtained from the addition polymerisation of: a) at least one polyamide prepolymer having n identical X functions selected among carboxy, amine and hydroxyl; and b) at least one non-polymer reactive extender having two identical Y functions which are reactive with said X functions, wherein n ranges from 1 to 3, said polyamide and prepolymer a) including 55-95 mol % of amide A units and 5-45 mol % of amide B units, wherein A corresponds to x.T in which x is a C9-C18 linear aliphatic diamine, and B corresponds to x'.T in which x' can be B1): a specific branched aliphatic diamine dependent on x, B2): MXD, or B3): a linear aliphatic diamine dependent on x, said polyamide having a glass transition temperature of at least 90 °C and a melting temperature no higher than 280 °C. The invention also relates to a method for manufacturing said composite material, to the use of the composition of the invention for composite material parts, and to said parts.
