EPOXY RESIN COMPOSITION, RESIN CURED PRODUCT, FIBRE-REINFORCED COMPOSITE MATERIAL, AND PREPREG

摘要

A cured product of an epoxy resin composition is provided which, as a result of controlling the composition and phase separation structure of the epoxy resin composition, exhibits a superior balance between rigidity and ductility when compared with cured products of conventional epoxy resin compositions. As a result of curing an epoxy resin composition comprising an epoxy resin, polyrotaxane having the ring molecule thereof modified by a graft chain, and a curing agent for the epoxy resin, a cured product of the epoxy resin composition can be obtained which exhibits both superior rigidity and superior ductility when compared with conventional materials.
