ABSTRACT:
The invention relates to a method of manufacturing a composite material formed by an organic substrate reinforced by glass strands. The invention consists of the combination of an organic substrate and glass strands coated with a sizing composition constituted by a solution with a solvent content of less than 5% by weight, the said solution comprising a mixture of components which can be polymerized and/or cross-linked by heat treatment, amongst the said components, at least 60% being components with molecular weights (Mw) of less than 750, and from 0 to 25% by weight being coupling agents, lubricating agents, stabilizing agents, polymerization initiators and/or catalysts, the said agents and initiators optionally being capable of being polymerized and/or cross-linked, the said sizing composition being non-polymerized, and of the subsequent subjection of the assembly to heat treatment and/or to the action of actinic radiation.
