Abstract: A molding composition including 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 (Bal) and polyether units (Ba2), (B) 5% to 30%, particularly 10% to 20%, more particularly 12.5% to 17.5% of carbon fibers, (C) 5% to 20%, particularly 10% to 15% of a hollow glass reinforcement, (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%.

Abstract: Molding composition, including by weight: (A) from 38 to 79.5% of at least one semi-crystalline aliphatic polyamide with the exclusion of PA6 and PA66, (B) from 10 to 20% of carbon fibres, (C) from 10 to 20% of hollow glass beads, (D) from 5.5 to 10% of at least one impact modifier having a flexural modulus of less than 200 MPa, in particular less than 100 MPa, as measured according to standard ISO 178: 2010, at 23° C., and (E) from 0.1 to 1% by weight of at least one additive, the sum of the proportions of each constituent (A)+(B)+(C)+(D)+(E) of the composition being equal to 100%.
