EPOXY RESIN COMPOSITION AND FILM, PREPREG, AND FIBER-REINFORCED PLASTIC USING SAME

摘要

The present invention relates to an epoxy-resin composition comprising the following components (A), (B), (D) and (E), a film made of the epoxy-resin composition, a prepreg and a fiber-reinforced plastic. The present invention can provide an epoxy resin composition capable of achieving both a processability of a prepreg at room temperature and a suppression of voids in the molded product. Also, the present invention can provide a fiber-reinforced plastic having excellent mechanical properties, especially excellent fracture toughness and heat tolerance, are obtained by using the epoxy-resin composition.
component (A): an epoxy resin having an oxazolidone-ring structure in the molecule;
component (B): a bisphenol bifunctional epoxy resin with a number-average molecular weight of at least 600 but no more than 1300, which does not have an oxazolidone-ring structure in the molecule
component (D): a triblock copolymer; and
component (E): a curing agent.
