Method of producing a resinous laminar body able to withstand temperatures above 150º c., without forming blisters and without separating the sheets, characterized by impregnating fibrous sheet material with a thermosetting resin, up to a relatively high resin content, which exceeds, for example, the weight of said sheet material; impregnating another sheet fibrous material with a thermosetting resin, to a relatively low resin content, for example, substantially less than the weight of said sheet material, forming a sheet body comprising superimposed layers of said material on sheets of resin content relatively low, on which a surface sheet of said material is superimposed on sheets of relatively high resin content; subjecting the stacked laminar body to hot compression for a predetermined period of time; then momentarily relieve the pressure to allow gas to escape, and then apply pressure again until the transition to said thermoset state is substantially complete and said assembly is consolidated in the unit structure form and, if desired, apply a resinous coating pigmented and thermosetting to said relatively high resin content surface, and firing said coating at elevated temperature.
