method for producing fiber reinforced composite material, heat resistant mold material and heat resistant structural material using composite material

摘要

method for producing fiber reinforced composite material, and heat resistant mold material and heat resistant structural material using the composite material. The present invention relates to a method of producing a fiber reinforced composite material, wherein a fiber reinforced prepreg obtained by impregnating the reinforcement fibers with an epoxy resin composition comprising formula 1 (a), n, n , n 39, n 39 -tetraglycidyldiammonodiphenylmethane (b) and diaminodiphenylsulfone (c), are subjected to primary cure at 110-1130 198 c, and then to secondary cure at a temperature that is at least as high as the primary cure temperature.
