Abstract

A nonswelling mass of fibers and a thermosetting synthetic resin are cold pressed into a preform body having a predetermined primary volume. This preform body is then hot pressed into an intermediate body having a secondary volume smaller than the primary volume. The press is then opened and a thermosetting synthetic-resin skin is applied to at least a portion of the surface of the intermediate body. Thereafter the skin and body are together pressed into a final integrated body having a volume smaller than the secondary volume. The skin is applied to the intermediate body as a foil.
