Title:
繊維強化プリプレグ及びそれから得られる複合材料
Document Type and Number:
Japanese Patent JP5451379
Kind Code:
B2
Abstract:
The present invention provides a prepreg made by impregnating a resin composition into a fiber reinforcing material, the resin composition comprising 50 to 60 parts by weight of an aromatic bismaleimide (A), 30 to 40 parts by weight of an alkenylphenol ether compound (B) expressed by a specific general formula, 5 to 15 parts by weight of an alkenyl aromatic comonomer (C), and 1 to 10% by weight of a thermoplastic resin (D) soluble in (B) or (C) based on the total amount of (A), (B) and (C), the aromatic bismaleimide (A) including 90% by weight or more of bismaleimide diphenylmethane, and a composite material having a glass transition temperature of 260 to 350°C obtained by heat-curing the prepreg. The invention also provides a prepreg for obtaining a fiber-reinforced composite material excellent in solvent resistance, thermal oxidation resistance and the like while maintaining thermal resistance inherent in an aromatic bismaleimide resin used as a matrix resin and a fiber-reinforced composite material obtained from the prepreg.
