New thermoplastic composite panels with a foam core and glass-reinforced skins can be heated and shaped, even with molded-in ribs, and they accept metal fastener inserts.

New thermoplastic composite panels with a foam core and glass-reinforced skins can be heated and shaped, even with molded-in ribs, and they accept metal fastener inserts. Poly-Kore panels come in a range of densities from High Impact Technology (HIT), Tigard, Ore., a fabricator of composites for military and commercial uses. The panels have skins of ThermoPro composite tapes bonded to a proprietary polyolefin foam core. ThermoPro tapes of polypropylene and 60% to 70% unidirectional or cross-ply (0/90°) continuous glass fibers are supplied by Polystrand, Inc., Montrose, Colo. The panels are heated outside the mold and shaped under very low pressure in cold tools. Testing of Poly-Kore panels is under way. HIT says screw retention is very good, and the foam core material has already earned an FAA fire rating for aviation uses. Fire and smoke testing is planned for Amtrak light-rail applications. Future developments may include a paint-ready surface for automotive. HIT: (503) 639-0044/www.hit-usa.com . Polystrand: (970) 240-2233/www.polystrand.com
