3A Composites Core Materials AIREX® C70.75 Universal Structural Foam
Categories: Other Engineering Material; Composite Core Material; Polymer

Material Notes: AIREX® C70 is a closed cell, crosslinked polymer foam that 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® C70 is ideally suited as a core material for a wide variety of lightweight sandwich structures subjected to both static and dynamic loads.

Characteristics

  • outstanding strength and stiffness to weight ratios
  • Good impact strength
  • Low resin absorption
  • High fatigue resistance
  • Good fire performance (self-extinguishing)
  • Sound and thermal insulation
  • Good styrene resistance
Applications
  • Marine: Hulls, decks, bulkheads, superstructures, interiors
  • Road and Rail: Roof panels, interiors, floors, doors, partition walls, side skirts, front-ends
  • Aircraft: Interiors, radomes, galley carts, general aviation (fuselage and wing)
  • Recreation: Skis, snowboards, surfboards, wakeboards, canoes, kayaks
  • Industrial: Tooling, tanks, ductwork, containers, covers
  • Vendors:
