Title:
RESIN COMPOSITION FOR FIBER-REINFORCED COMPOSITE MATERIAL, AND PREPREG AND FIBER-REINFORCED COMPOSITE MATERIAL OBTAINED USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/217706
Kind Code:
A1
Abstract:
The present invention provides a fiber-reinforced composite material which exhibits excellent heat resistance and exhibits superior mechanical strength compared to a material obtained by mixing reinforcing fibers with a bismaleimide resin and an alkenylphenol resin as resin components. The present invention relates to a resin composition for a fiber-reinforced composite material, which contains reinforcing fibers and a resin component. The resin component contains an allyl compound (A) having two or more allyl groups and one or more benzene rings per molecule; a maleimide compound (B) having two or more maleimide groups per molecule; and a thiol compound (C) having two or more thiol groups per molecule. Relative to 100 parts by weight of the allyl compound (A), the polymerization ratio of the maleimide compound (B) is 155-530 parts by weight and the polymerization ratio of the thiol compound (C) is 15-120 parts by weight.
