摘要
PROBLEM TO BE SOLVED: To obtain an epoxy resin composition used to bond fiber-reinforced sheets, which composition comprises an epoxy resin which develops a specified or lower compressive modulus after being cured, desirably, an epoxy resin of a two-package type. ;SOLUTION: This composition comprises an epoxy resin which develops a compressive modulus of below 980 N/mm2 after being cured. This can be realized by adjusting the crosslinking density, epoxy equivalent, and structure of the epoxy resin, or by adjusting the active hydrogen equivalent of a curing agent in a two-package epoxy resin. The compressive modulus can be heightened by heightening the crosslinking density, and it can be lowered by lowering the crosslinking density. The compressive modulus can be lowered by heightening the epoxy equivalent, and it can be heightened by lowering the epoxy equivalent.;COPYRIGHT: (C)2000,JPO
