ABSTRACT:
A process for preparing GMT/foam composites in an integral process without the prior preparation of a separate consolidated GMT part produces lightweight load-bearing structures suitable for use as vehicle components such as load floors, seatbacks, and the like. The structures have fully GMT-encapsulated foam cores abutting at least partially consolidated GMT layers and at least one fully densified GMT portion. The structures may be economically and rapidly molded without resort to necessary adhesives for assembly.
