Abstract
A method of molding a hollow, reinforced molded plastic article. A preform is provided in the shape of the article to be molded. The preform comprises randomly commingled, short lengths of thermoplastic and reinforcing fibers loosely bonded together.

The preform is placed in a mold and heated to fuse the thermoplastic while a pressurized liquid coolant is circulated within the core.
