    摘要: Thermoplastics reinforced with glass fiber mats contain from 10 to 60% by weight of such mats and from 5 to 60% by weight of a finely divided inert filler, the sum of the percentages by weight of glass fiber mats and filler being not greater than 70% by weight. The inert filler is a talc, having a foliated crystalline structure, which has a mean flake thickness of not more than 5 .mu.m and a ratio of mean flake diameter to mean flake thickness of from 5:1 to 500:1. When processing the thermoplastic filled with talc and glass fiber mats, homogeneous impregnation of the glass fiber mats with the filled thermoplastic is achieved.
