Title:
EPOXY RESIN COMPOSITION FOR FIBER-REINFORCED COMPOSITE MATERIAL, FIBER-REINFORCED COMPOSITE MATERIAL AND MOLDED BODY
Document Type and Number:
Japanese Patent JP2019104891
Kind Code:
A
Abstract:
To provide an epoxy resin composition for fiber-reinforced composite material which is excellent in dynamic characteristics of a molded article while achieving both impregnation property and storage stability in prepreg production.SOLUTION: An epoxy resin composition for fiber-reinforced composite material contains an epoxy resin (A), dicyandiamide (B), an imidazole-based curing auxiliary (C) and a core shell rubber (D) as essential components, in which the imidazole-based curing auxiliary (C) has a heat generation starting temperature when the epoxy resin composition is measured by DSC on the condition of a temperature rise rate of 10°C/minute of 135°C or higher.SELECTED DRAWING: None
