Title:
エポキシ樹脂組成物、プリプレグ、繊維強化プラスチック材料および繊維強化プラスチック材料の製造方法
Document Type and Number:
Japanese Patent JP6658747
Kind Code:
B2
Abstract:
The present application provides a rapid curing epoxy resin composition for fiber-reinforced plastic materials that can be used with modern fast-cure heating systems without loss of heat resistance, surface quality, or mechanical properties of the cured epoxy matrix composite as well as prepregs and fiber-reinforced plastic materials based thereon as their matrix resins. The epoxy resin composition includes an epoxy resin, a dicyandiamide, an aromatic urea, and a clathrate complex comprising at least one compound selected from the group consisting of carboxylic acid compounds and tetrakisphenol compounds and at least one epoxy accelerator which is an imidazole and/or imidazoline.
