Abstract
A process for forming reinforcing layers or films on the complicated configured interior surfaces of a unitary molded plastic body consisting of providing soluble or meltable inert core member, applying ceramic or metallic reinforcing layers or films onto outer surfaces of the core member except its longitudinal ends, placing the core member covered with the reinforcings in the mold cavity, molding a plastic body around and integrally with the reinforcing layers or films on the core member, and fluidizing the core member to remove the same from the interior of said plastic body leaving the reinforcing layers or films on the interior surfaces of the plastic body.
