Abstract

The process comprises mixing chopped glass fibres in filamentary form with plastics-forming ingredients and moulding or forming the mixture to obtain reinforced plastics articles. Conveniently the glass fibres are first made into a slurry or paste, with a liquid compatible with the plastics-forming ingredients or with all or a part of one or more of the ingredients.
