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

摘要

An epoxy resin composition comprising the following constituents [A], [B] and [C]: [A] an epoxy resin having a structure represented by formula (1) (wherein the ring Z represents a condensed polycyclic aromatic hydrocarbon ring; R1 and R2 independently represent a substituent; R3 represents a hydrogen atom or a methyl group; k represents an integer of 0 to 4; m represents an integer of 0 or more; and n represents an integer of 1 or more); [B] at least one resin selected from the group consisting of [Bx] a bisphenol-type epoxy resin, [By] an amine-type epoxy resin and [Bz] a thermoplastic resin; and [C] a polyamine curing agent. Provided is an epoxy resin composition which enables the production of a cured article having excellent heat resistance, toughness and elastic modulus.
