Abstract (en)
[origin: WO2007116191A1] The invention relates to glass filaments which are intended for reinforcing polymeric materials and which are coated with a sizing composition comprising, as adhesive film-forming agents, a mixture of at least one polyvinyl acetate and at least one polyvinylpyrrolidone, said at least one polyvinyl acetate representing 70% to 90% by weight of the solids of the size. The resulting glass filaments are used as reinforcements in the production of mouldings having a thermosetting matrix that are obtained by simultaneous spraying of said filaments and resin, in particular by LFI (Long Fibre Injection) moulding.
