A panel having a honeycomb core and thermoplastic resin facings with adhered decorative polyvinyl fluoride overlayer is shaped in a press after being preheated to the softening temperature of the resin and the placing of the heated thermoplastic resin facing in registry with the overlayer which is preheated, thus pressing the two together in the press.

A process for fabricating panels of a core material with thermoplastic resin facings. The core material is either foam or a honeycomb structure from aramid paper. A belt press machine provides a means for rapid heating and cooling such that the core will not degrade. Since the process is so rapid, aramid fibers can be used to reinforce the resin facings without deleterious decomposition of the fibers under the temperatures used to heat the panels during forming.

Less porous, more abrasion-resistant nonwoven aramid sheets are made by expanding a smooth-surface, dried, wet-laid sheet of fibrids and fibers, which has fused, nonexpandable, densified regions, segmented by spaced interruptions of nonfused regions of the sheet structure, in a pattern which encloses expandable portions of the sheet structure. The re-wet sheet is heated dielectrically to expand the interior of the nondensified portions without substantially roughening or disrupting their surface skin.
