Title:
THERMOSETTING RESIN COMPOSITION FOR FIBER-REINFORCED COMPOSITE MATERIAL, PREFORM, FIBER-REINFORCED COMPOSITE MATERIAL, AND METHOD FOR PRODUCING FIBER-REINFORCED COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/065432
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a thermosetting resin composition for a fiber-reinforced composite material, the thermosetting resin composition having an excellent balance of rapid curability and storage stability as well as excellent handleability at normal temperature and ability to impregnate a reinforcing fiber base material; and a preform for a fiber-reinforced composite material and a fiber-reinforced composite material that use the same. To achieve this purpose, the first embodiment of the thermosetting resin composition for a fiber-reinforced composite material according the present invention has the following constitution. Specifically, a thermosetting resin composition for a fiber-reinforced composite material having domains of each of [A] a base compound and [B] a curing agent and/or [C] a catalyst and having a specific gravity of 0.90-1.30 and a complex viscosity η* of 1 x 107 Pa∙s or higher in dynamic viscoelasticity measurement at 25°C.
