Patent number: 10829603Abstract: There is provided a cured product of an epoxy resin composition, in which the compounding composition and the phase-separated structure of the epoxy resin composition are controlled so that the balance between rigidity and toughness of the cured product is superior compared with those of cured products of conventional epoxy resin compositions. A cured product of an epoxy resin composition, which has both superior rigidity and superior toughness compared with conventional materials can be produced by curing an epoxy resin composition comprising an epoxy resin, a polyrotaxane having graft-chain-modified cyclic molecules and a curing agent for the epoxy resin.Type: GrantFiled: February 17, 2015Date of Patent: November 10, 2020Assignee: TORAY INDUSTRIES, INC.Inventors: Keiichiro Nomura, Nobuhiro Morioka, Kentaro Sano, Noriyuki Hirano, Sadayuki Kobayashi
