EPOXY RESIN COMPOSITION, AND FIBER-REINFORCED COMPOSITE MATERIAL PRECURSOR AND FIBER-REINFORCED COMPOSITE MATERIAL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a fiber-reinforced composite material excellent in fatigue resistance characteristics under a condition high in repeated load stress.SOLUTION: There is provided an epoxy resin composition containing following component (A) and component (B), in which a cured article does not rupture when flexural strain of the cured article of the composition is 1.5 times or less of strain at a flexure maximum load. Component (A): an epoxy resin having an oxazolidone ring structure. Component (B): a curing agent.SELECTED DRAWING: None
