Reinforced plastic article - by impregnating fabric with first resin curing at high temp and then with second resin curin

摘要

Plastic article reinforced with a fibrous mat or fabric is produced by (a) impregnating the reinforcement under pressure with a first synthetic resin mixed with a catalyst and an accelerator, the first synthetic resin not curing at normal room temp., (b) adding a second synthetic resin to form a laminate consisting of several layers reinforcing material, the second synthetic resin conts. a catalyst and an accelerator of such composition that the curing reaction of the second synthetic resin is sufficiently exothermic to activate the catalyst for and cure the first synthetic resin. Process removes air from the reinforcing material.
