Composition of epoxy resin, curing agent and reactive compound

Epoxy resin compositions, epoxy resin compositions for fiber-reinforced composite materials, and fiber-reinforced composite materials comprising the same

Prepeg and carbon fiber reinforced composite materials

The invention provides a resin composition for a fiber reinforced composite which can be used to produce a prepreg excellent in tackiness, drapability and windability around a mandrel, and also provides a prepreg in which reinforcing fibers are impregnated with a resin composition, and a fiber reinforced composite obtained from them. The resin composition includes a thermosetting resin and a thermoplastic resin with a weight average molecular weight of 200,000 to 5,000,000.

Resin composition for a fiber reinforced composite, a prepreg and a fiber reinforced composite

Disclosed are epoxy resin compositions for fiber-reinforced composite materials, comprising an epoxy resin containing 70 parts by weight or more, per 100 parts by weight of the epoxy resin, of a bi-functional epoxy resin, fine particles comprising a rubber phase and substantially insoluble in epoxy resins and a curing agent. Also disclosed are prepregs and fiber-reinforced composite materials comprising the composition.

Prepreg of reinforcing fibers, epoxy resins, crosslinked rubber

A composition is useful as a prepreg containing reinforcing fibers comprises an epoxy resin, a thermoplastic elastomer of a polyamide and/or polyester block copolymer, a curing agent such as dicyandiamide, and optionally a thermoplastic resin such as a polyvinyl formal resin.
