ABSTRACT:
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.
