Core Materials

Increased Stiffness & Decreased Weight ◾ Corrosion Resistance ◾ Great Thermal Properties

Core materials are generally used for "sandwich structured" composites which is a special class of composite materials that is fabricated by attaching two thin, but stiff skins to a lightweight, but thick core. The core material is normally low strength material, but its higher thickness provides the sandwich composite with high bending stiffness with overall low density.

Nomex® Honeycomb is an aerospace grade aramid fiber honeycomb exhibits outstanding flammability properties. It is manufactured from DuPont Nomex® paper (or equivalent) and coated with a heat resistant phenolic resin. Nomex core honeycomb uses include aircraft galleys, flooring, partitions, aircraft leading and trailing edges, missile wings, radomes, antennas, military shelters, fuel tanks, helicopter rotor blades and navy bulkhead joiner panels.

Aluminum Honeycomb PCGA-XR2 3003 commercial grade aluminum honeycomb is a lightweight core material offering excellent strength and good corrosion resistance for industrial applications at low cost. PCGA-XR2 3003 honeycomb (currently the only aluminum honeycomb Rock West offers) is made from 3003 aluminum alloy foil. Honeycomb uses include air/light directionalization, energy absorption, tooling, ceiling and floor panels, counter tops and other applications for which elevated physical and mechanical properties are not required.

ROHACELL® Foam is a closed-cell rigid foam based on polymethacrylimide (PMI) chemistry, which does not contain any CFC's and is commonly used in aerospace, transportation and marine applications. We offer ROHACELL foam in numerous densities and size options.
