Abstract
The subject invention relates to methods and materials for making porous resin rigidified shaped articles suitable for filters, surgical trays, and the like, which comprises the steps of impregnating a non-woven fabric with a predetermined amount of thermoplastic or thermosetting water-based epoxy resin; partially curing the resin-impregnated fabric; and, thereafter molding the partially cured fabric into a desired shape with sufficient heat to advance the curing of the resin.
