ABSTRACT:
A manufacturing process for reverse building complex-shaped vehicle fuel tanks using complementary female mold halves which, when joined together about their mating peripheral edges, exactly duplicate the vehicle body cavity into which the completed tanks are to be mounted. Plies of a urethane elastomer are spray-coated into the molds and nylon fabric reinforcement is applied in two steps to complete the composite which forms the tank structure. Upon completion of forming of the composite, the mold halves are joined and a splice is completed from the inside of the tank by laying in reinforcement fabric at the butt joined sections of the composite and sealing it with urethane elastomer.
