PK2 Para-Aramid Fiber Honeycomb

Description: PK2 para-aramid fiber honeycomb is an extremely lightweight, high strength, non-metallic honeycomb manufactured with para-aramid fiber paper impregnated with a heat resistant phenolic resin. This core material exhibits improved performance characteristics over Meta-Aramid in the areas of weight, strength, stiffness and fatigue.
Features: • Up to 40% higher properties than comparable density meta-aramid honeycomb
• Extremely high strength-to-weight ratio
• Excellent thermal and moisture stability
• Improved shear strength and modulus
• Conforms to stringent smoke, toxicity and flammability standards
• High toughness
• Compatible with most adhesives used in sandwich composites
• Long shelf life. The mechanical properties referenced are maintained for 10 years minimum if not exposed to moisture, weather or any normal hazard.
Applications: PK2 honeycomb is a high performance non-metallic core which can replace fiberglass and Nomex® honeycomb core materials to achieve significant weight reductions without sacrificing performance in most applications. PK2 para-aramid fiber honeycomb uses include boat decks, aircraft galleys, flooring, partitions, aircraft leading and trailing edges, radomes, flaps, access panels and doors.
PK2 honeycomb is available in sheets, blocks or cut to size pieces in regular hexagonal configurations. Selected densities available in high shear (HS) configuration for higher stiffness.
