Abstract (en)
[origin: WO2022079380A1] The present invention relates to a moulding composition comprising by weight: (A) 45% to 90%, particularly 60% to 80%, more particularly 62.5% to 77.5% of at least one copolyamide with amide units (Ba1) and polyether units (Ba2); (B) 5% to 30%, particularly 10% to 20%, more particularly 12.5% to 17.5% of carbon fibres; (C) 5% to 20%, particularly 10% to 15% of a hollow glass reinforcement; and (D) 0 to 5%, preferably 0.1% to 2% of at least one additive; the sum of the proportions of each constituent (A) + (B) + (C) + (D) of the composition being equal to 100%.
