| 摘要 |
The invention relates to a sizing composition for reinforcing fibres, which makes it possible to improve the adhesion of these fibres with respect to an organic matrix that forms, with them, a part made of a composite material and that results from the chain transfer polymerization of a curable resin, and also to applications of this composition. The sizing composition comprises a polybutadiene prepolymer comprising at least two epoxide functions, a crosslinking agent comprising at least two reactive functions, at least one of which is a thiol function, and a catalyst comprising at least one tertiary amine function. Fields of use: aeronautical, aerospace, railway, naval and motor vehicle industries, for example for the production of structural, engine, passenger compartment or body work parts; arms industry, for example for the production of parts incorporated into the composition of missiles or missile launch tubes; sports and leisure goods industry, for example for the production of goods intended for water sports and board sports. |
