Abstract

Filler-containing thermoplastic molding materials contain, as essential components, PA1 A) from 10 to 84.8% by weight of a thermoplastic polyamide, PA1 B) from 10 to 84.8% by weight of a modified polyphenylene ether, PA1 C) from 5 to 50% by weight of glass fibers or carbon fibers or a mixture thereof, having a median fiber length 1.sub.50 of from 150 to 400 .mu.m, and PA1 D) from 0.2 to 4% by weight of a pigment and in addition PA1 E) from 0 to 4% by weight of a rubber impact modifier, PA1 F) from 0 to 20% by weight of a particulate filler which differs from D) and PA1 G) from 0 to 20% by weight of a flameproofing agent.
