Abstract:
A process for forming a moldable, uncured nonwoven composite containing forming a structural nonwoven layer, at least partially impregnating the structural nonwoven layer with an uncured, water-based thermosetting resin having a cure temperature of at least about 160° C., and at least partially drying the uncured, wet nonwoven composite. The structural nonwoven layer contains a plurality of binder fibers and a plurality of reinforcing fibers which are cellulosic fibers. Heat and pressure are applied to the moldable, uncured composite to a temperature of at least about 160° C. at least partially melting the binder fibers, curing the water-based thermosetting resin, and bonding at least a portion of the reinforcing fibers to other reinforcing fibers forming the molded, cured composite. The reinforcing fibers react with and form covalent bonds with the thermosetting resin.
