ABSTRACT:
This invention relates to an improvement in the process of preparing an article of a reinforced thermosetting resin. The known process comprises a) impregnating a foam sheet with a curable thermosetting resin, b) applying a layer of fibrous reinforcing material to a side of the impregnated foam sheet, c) compressing the impregnated foam sheet so that the resin impregnates the fibrous material, and d) allowing the sheet and layer to cure while compressed. The improvement of this invention comprises effecting the compression of the foamed sheet and fibrous material by the expansion pressure of a foaming composition.
