Abstract
PURPOSE:To obtain the titled prepreg having excellent toughness, impact resistance, tensile strength and interlayer shear strength, by impregnating reinforcing fibers with a polymer composition composed of a specific epoxy polymer, a resorcin-type polysulfone and a hardener for epoxy polymer. CONSTITUTION:The objective prepreg can be produced by impregnating reinforcing fibers with a polymer composition composed mainly of (A) an epoxy polymer composed mainly of at least one kind of polymer selected from bisphenol F-type epoxy polymer, bisphenol A-type epoxy polymer, bisphenol AD-type epoxy polymer and aminophenol-type epoxy polymer, (B) a resorcin-type polysulfone having a phenolic hydroxyl group at the molecular terminal and an number- average molecular weight of 3,000-30,000 and (C) a hardener for epoxy polymer (e.g. diaminodiphenylsulfone compound).
