The STRATA process

1 A thermoplastic sheet is thermoformed, heated, then placed in an open mold and vacuum formed to its finished shape. Reinforcement fibers are applied to the inner and outer plastic skins. The reinforced fiber-backed skins are placed in the liquid molding press.

2 The press is closed and urethane foam is injected.

3 The finished part shows a cross section of the integrated composite sandwich structure.
