TWO-PACK TYPE EPOXY RESIN COMPOSITION FOR FIBER-REINFORCED COMPOSITE MATERIALS, AND FIBER-REINFORCED COMPOSITE MATERIAL

摘要

Provided are: a two-pack type epoxy resin composition which has excellent workability during preparation of a resin, maintains low viscosity when poured onto reinforcing fibers and thus exhibits excellent impregnation properties, is cured in a short time when molded, and provides a fiber-reinforced composite material having high dimensional accuracy; and a fiber-reinforced composite material which uses the two-pack type epoxy resin composition. A two-pack type epoxy resin composition for fiber-rein-forced composite materials, which contains the components [A]-[D] described below, and wherein the component [D] is in a liquid state at room temperature or is in a solid state that has a melting point of 90°C or less. [A] an epoxy resin [B] an acid anhydride [C] a compound that has an average of 2.5 or more hydroxyphenyl structures in each molecule [D] an organic phosphorus compound or an imidazole derivative
