ABSTRACT:
A process which includes comminuting a first thermoplastic material, e.g. polypropylene, reinforced with short glass fiber (10-400 .mu.m). 100 parts by weight of the comminuted material are mixed with 11-43 parts by weight of chips of a second thermoplastic material, which is reinforced with long glass fiber (about 10-20 mm). The melts of the two thermoplastic materials should be mutually mixable. The mixture is subjected to thermoplastic forming.
