  • Patent number: 4952358
    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.

  • Patent number: 4871612
    Abstract: An improved interior member for vehicles which includes a substrate containing a reinforcing fiber mat with a polyisocyanurate permeated therethrough and a surface layer integrally formed on the substrate. The amount of the polyisocyanurate is so determined that the density of the polyisocyanurate in said substrate is 1.2 to 1.9 times as much as the density of the same polyisocyanurate in its free foaming state. The surface layer may include a fabric, a resilient foam and a thermoplastic resin sheet in layers, or alternatively may include non-foamed plastic as an outer layer and foamed plastic as an inner layer. A method for manufacturing the above interior member for vehicles is neither complicated nor costly.

  • Patent number: 4455340
    Abstract: A flexible molded foam comprises a surface layer of elastic thin film, an intermediate reinforcing layer of elastic film and a core layer. The surface layer comprises a linear polymer, the intermediate reinforcing layer comprises a three-dimensionally crosslinked polyurethane and the core layer is composed of a semi-rigid polyurethane foam. These elements are integrally molded in a desirable shape.
