SIZED GLASS FIBRES WITH FAST IMPREGNATION FOR THE REINFORCEMENT OF POLYMER MATERIALS

摘要

The invention relates to glass fibres which are covered with a sizing composition comprising, by way of adhesive film-forming agents, at least one polyester, at least one polyvinyl acetate and at least one polyurethane. The glass fibres thus obtained are used as reinforcement in the production of thermosetting matrix moulded parts obtained by means of open-mould moulding, for example, with the simultaneous projection of said fibres and resin, and tubes by means of centrifugation.
