Abstract (en)
[origin: WO2021255372A1] Moulding composition, comprising 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; and • (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, • (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 said composition being equal to 100%.
