摘要:
A method for producing a prepreg roving, which comprises impregnating a composition comprising an unsaturated polyester, an unsaturated monomer (e.g. styrene) and a polyisocyanate compound (e.g. 4,4'-diphenylmethane diisocyanate) in a filamentary reinforcing material (1) (e.g. a glass roving) and then heating the impregnated reinforcing material to react the unsaturated polyester with the polyisocyanate compound, thereby bringing the resin to the B-stage; and a method for producing a fiber-reinforced plastic article, which comprises disposing prepreg rovings (A), said prepreg rovings being prepared by the above method between at least two plies of sheet molding compound (B) obtained by impregnating a composition comprising an unsaturated polyester and an unsaturated monomer in glass fibers and forming the impregnated product into a sheet; and consolidating the resulting assembly under heat and pressure. - Figure 1 is a flow chart showing the production of the prepreg roving mentioned above.
