Title:
PREPREG AND FIBER-REINFORCED COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/021146
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a prepreg which satisfies one of a)-c): a) having superior storage stability and capable of providing a fiber-reinforced composite material having superior mechanical properties; b) capable of providing a fiber-reinforced composite material having superior mechanical properties, and the obtained fiber-reinforced composite material has superior appearance quality; and c) having superior storage stability, generating less amount of heat when cured, and enabling the cure extent and the viscosity in the B-stage state to be flexibly controlled. To achieve the purpose, the present invention provides a prepreg including reinforced fibers and an epoxy resin composition which contains an epoxy resin and a curing agent represented by a specific chemical formula, and which satisfies a specific condition.
