Abstract
A manufacturing device has an outer chamber in which a tool is mounted. The tool is shaped to receive a thermoplastic or staged prepreg. The tool has heaters embedded within it. The chamber region between the tool and the inside wall of the chamber is filled with polysilicone polymer and pressurized to a low pressure such as 50 pounds per square inch. To insure prepreg compaction the chamber is then pressurized in the range of 3,000 pounds per square inch. The chamber to insure prepreg compaction is then pressurized and as is the polysilicone polymer to a pressure in the range of 3,000 psi. At the completion of the temperature/pressure cycle, the cured product is removed from the tool.
