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 such that the temperature at the inner plane is less than about 130° C. forming an moldable, uncured composite. The structural nonwoven layer contains a plurality of bi-component binder fibers and a plurality of reinforcing fibers, the bi-component fibers containing a core and a sheath. The core contains a polymer having a melting temperature of at least about 180° C. and the sheath contains a polymer having a melting temperature less than about 180 ° C. A process for forming a molded, cured composite containing forming a structural nonwoven layer and a molded cured nonwoven composite are also disclosed.
