ABSTRACT:
Two sheets of an air impermeable plastic coated fabric are placed horizontally, with a core of a resilient open cell foam material positioned between the two sheets. Heated platens are applied to this layup, followed by applying a vacuum to the interior, cooling the assembly, and then moderately pressurizing the then bonded assembly.
