Abstract
The invention relates to a polyamide moulding compound consisting of the following components: (A) 35-68 wt. % of at least one semi-crystalline, semi-aromatic, thermoplastic polyamide based on aliphatic diamines with 4-8 carbon atoms with a melting temperature of at least 270° C.; (B) 15-22 wt. % carbon fibres; (C) 18-30 wt. % glass fibres; (D) 1-10 wt. % of an impact-resistance modifier that is different from (E) and/or polymers that are different from (A), (E) and (F); (E) 0-10 wt. % ethylene-vinyl acetate copolymer; and (F) 0-3 wt. % additives. In this way, the sum of the components (A)-(F) is 100 wt. %, the sum of the components (B)-(C) is in the range of 33-48 wt. %, and the sum of the components (D)-(E) is in the range of 2-12 wt. %. The moulding compound permits the production of dimensionally stable, electrically conductive components, e.g. for the automotive sector and for contact with fuels, in particular methanol-containing petrol.
