Abstract
An amorphous hydrated metal oxide primer for fibers incorporated into fiber reinforced polymeric matrix composites result in composites having wet strength retention. The layer of amorphous hydrated metal oxide is formed by depositing on the fiber and subsequent hydrolysis of a layer of M.sub.x OR.sub.y where x is 1, y is 3 or 4, M is any metal capable of forming a stable alkoxide and R is an organic radical. Fiber reinforced polymeric matrix composites are preferably made by applying a layer of M.sub.x OR.sub.y to the fiber where x is 1, y is 3 or 4, M is any metal capable of forming a stable alkoxide and R is an organic radical. The fiber having a layer of metal alkoxide is exposed to moisture and a temperature of about 25.degree. C. to about 125.degree. C., impregnated with a resin and stacked in a mold. The stacked impregnated fibers are then pressed with optional heat resulting in a composite having wet strength retention.
