3A Composites Core Materials AIREX® C71.75 Elevated Temperature Structural Foam

AIREX® C71 is a closed cell, crosslinked polymer foam especially formulated to maintain its stability also at higher processing or service temperatures. It combines excellent stiffness and strength to weight ratios with superior toughness. It is non-friable, contains no CFC’s, has negligible water absorption, and provides an excellent resistance to chemicals. A fine cell structure offers an excellent bonding surface. Compatible with most resins and manufacturing processes AIREX® C71 is ideally suited as a core material for a wide variety of lightweight sandwich structures subjected to both static and dynamic loads, and exposed to elevated temperatures during manufacturing.Characteristicsoutstanding strength and stiffness to weight ratiosHigh temperature resistanceGood impact strengthHigh fatigue resistanceLow resin absorption (fine cell structure)Good fire performance (self-extinguishing)Sound and thermal insulationGood styrene resistanceDimensionally stable and non biodegradableApplicationsWind Energy: Rotor blades, nacelles, turbine generator housingsRoad and Rail: Roof panels, interiors, floors, doors, partition walls, side skirts, front-endsMarine: Hulls, decks, bulkheads, superstructures, engine hatchesAircraft: Interiors, radomes, galley carts, general aviation (sport aircraft)Recreation: Skis, snowboards, surfboards, wakeboards, canoes, kayaksIndustrial: Tooling, tanks, ductwork, containers, covers
