EPOXY RESIN, METHOD FOR PRODUCING EPOXY RESIN, CURABLE RESIN COMPOSITION AND CURED PRODUCT THEREOF, FIBER-REINFORCED COMPOSITE MATERIAL, AND MOLDED ARTICLE

摘要

Provided is an epoxy resin which has a low viscosity and excellent impregnation capability into reinforcing fibers and provides a cured product having a high elastic modulus and excellent heat resistance when the epoxy resin is used for a fiber-reinforced resin material, and a method for producing the epoxy resin, a curable resin composition, and a cured product thereof, a fiber-reinforced composite material, and a molded article. An epoxy resin which is polyglycidyl ether that is a polycondensation product of phenol and hydroxybenzaldehyde, the resin includes the trinuclear body (X) represented by the following Structural Formula (1), in which the content of a [o,p,p] bonding body (x1) represented by the following Structural Formula (1-1) among the trinuclear body (X) is in the range of 5% to 18% in terms of an area ratio as measured by liquid chromatography.;
