A process for making abrasion-resistant composites is disclosed. The
process comprises the steps of providing a fibrous sheet containing a
high density of relatively short staple fibers having a decitex under
6.6; needle-punching the staple layer and applying an adhesive containing
layer; followed by the application of heat and pressure to the composite
to form a thin consolidated and abrasion-resistant back-face layer on the
composite. Preferably, the adhesive layer is penetrated by the needled
fibers during the needling step and the product is shrunk in area by
20-50% before the consolidation step. Also optionally, the consolidated
layer is abraded or perforated to create micro-pores that are permeable
to gases and capable of containing liquids under low-to-moderate
pressures.
