PURPOSE:To provide the title compsn. which has excellent resistance to heat, impact and moisture and is suitable for use in impregnating carbon fiber having high elongation and medium modulus of elasticity, consisting of a resin composed of a cyanic ester component and a maleimide component, a liquid epoxy resin and a specified satd. polyester. CONSTITUTION:96-40 wt. resin (A) composed of a cyanic ester component and a bismaleimide component (e.g., a bismaleimide/triazine resin) is mixed with 2-50 wt% liquid epoxy resin (B) having an MW of not higher than 500 and an epoxy equivalent of not higher than 300, such as a diepoxide of a bisphenol, and 2-20 wt% satd. polyester (C) having a glass transition temp. of not lower than 40 deg.C at 150-200 deg.C. The mixture is mixed while heating at 80-120 deg.C. If desired, a catalyst (D) (e.g., triethylamine) is added thereto. |
