Abstract

In a fiber composite plastic composed of plastic composition and fibers, the fibers have a pronounced fiber length distribution, in particular more than 50% by weight of the fibers have a length outside the range from 0.8.times.L to 1.2.times.L, where L is the mean (weight average) fiber length, and the mean fiber length is greater than the critical fiber length of the plastic composition/fiber system.
