Title:
プリプレグ、炭素繊維強化複合材料、ロボットハンド部材及びその原料樹脂組成物
Document Type and Number:
Japanese Patent JP6397205
Kind Code:
B2
Abstract:
Provided are a carbon-fiber-reinforced composite material having a low saturated water absorption and excellent TML, CVCM, and heat resistance, a robot hand, and a prepreg suitable therefor. The prepreg includes a CFRP sheet composed of resin composition (a) containing 100 parts by mass of cyanate ester resin (a1) having in its molecule not less than 2 cyanate groups, 0.01 to 0.5 parts by mass of metal coordination catalyst (a2), and 1 to 20 parts by mass of thermoplastic, toughness enhancer (a3), and carbon fibers (b) containing carbon fibers (b1) having a tensile elastic modulus of not lower than 450 GPa. The prepreg is useful for a supporting section of a robot hand.
