Abstract
Moulding materials composed of glass fibre-contg. synthetic resins are produced with a heated screw extruder, which is supplied with at least partly solid synthetic resin, opt. additives such as dyes and fillers, and with endless glass fibre cords, at least the major part of these cords being supplied to the extender by an opening situated at a place where the base material is present at least partly in a molten state, and removed from the discharge opening of the extruder by a distance such that the cords are fragmented to a desired size, and a desired degree of homogenisation is attained. The process enables glass fibre-reinforced moulding materials to be obtd. in which the glass fibres are uniformly dispersed.
