3A Composites Core Materials AIREX® PXw.420 Fiber-Reinforced Structural Foam Panel
Categories: Other Engineering Material; Composite Core Material; Polymer

Material Notes: AIREX® PXw is a closed-cell, fiber reinforced polymer foam panel with a special formulation and very high mechanical properties. The sophisticated manufacturing process evenly distributes continuous glass fibers with woven fabrics throughout the foam. This generates a product with enhanced mechanical properties in flexure (bending), allowing it to be used with or without face sheets. AIREX® PXw is dimensionally stable, does not lose strength when wet, and is resistant to chemicals and high temperatures. It is ideally suited as a material for static applications requiring high stiffness or as a replacement for wood and plywood.

Characteristics

  • Stand alone product – does not need face sheets
  • High flexural strength and stiffness
  • Replacement for wood and plywood
  • Good fastener pull-out strength
  • High heat resistance
  • Compatible with a wide range of resins and adhesives
  • Dimensionally stable
  • High styrene resistance
  • Very low water absorption
  • Non biodegradable
  • Excellent chemical resistance
Applications
  • Marine: Floors, soles, bulkheads, transoms, stringers, engine beds, interiors, local reinforcements, tooling and molds
  • Road and Rail: Floors, sidewalls, roofs, engine covers, interior panels
  • Industrial: Covers, tanks, containers, floors, tooling and molds, concrete pouring forms, architectural panels, tub and shower enclosures
