RESIN COMPOSITION FOR FIBER-REINFORCED COMPOSITE MATERIAL, PREPREG AND FIBER-REINFORCED COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To obtain a resin composition for fiber-reinforced composite materials capable of imparting excellent mechanical characteristics to the composite material, a prepreg and the composite material having excellent mechanical characteristics. SOLUTION: This resin composition for fiber reinforced composite materials comprises 100 pts.wt. of (A) an aromatic epoxy resin, 2-15 pts.wt. of (B) an aliphatic epoxy resin and/or an alicyclic epoxy resin, 2-25 pts.wt. of (C) a phenoxy resin or a polyvinylformal resin and 5-12 pts.wt. of (D) an epoxy resin curing agent as essential ingredients.
