Abstract
PURPOSE: To obtain a prepreg sheet usable in the next stage favorably free from falling off of the resin in the cutting and transportation operations, having improved impregnation properties and heat resistance, by drying a slurry comprising a bisimide, a polyamine, and water applied to a fibrous substrate.
CONSTITUTION: A fibrous substrate is coated with a slurry composition comprising (A) one equivalent of a bisimide of the formula (A is bifunctional organic group having an ethylenic double bond; B is bifunctional organic group having an aromatic nucleus), (B) 0.1W2 equivalents of a polyamine of the formula R(NH2)n (R is n-functional organic group having an aromatic nucleus; n is an integer 2W 5), and (C) water, and dried to give a prepreg sheet. Preferably, the substrate is dried by a method to heat the slurry composition and to make the drying proceed simultaneously, preferably heat radiation. The slurry has a viscosity of 1W200 poises, preferably 5W120 poises.
