ABSTRACT:
A method for manufacturing an interior member for vehicles comprises the steps of laying a surface layer in a cavity of a mold, placing a reinforcing fiber mat onto the surface layer, compressing the surface layer and the reinforcing fiber mat in the mold, injecting raw material for obtaining a polyisocyanurate and demolding an integrally-molded interior member from the mold after the completion of a reaction of the raw material. The raw material comprises a trimerization catalyst, a polyol and a polyisocyanate. The amount of raw material is determined so that the density of the obtained polyisocyanurate is 1.2 to 1.9 times as much as the density of the same polyisocyanurate in its free foaming state.
