Product Data Sheet: CFOAM® Carbon Foams

CFOAM®, developed by Touchstone Research Laboratory, Ltd., is a next-generation structural carbon foam material which is inexpensive, lightweight, fire-resistant, impact-absorbing, thermally insulating or conducting, and with electrical conductivity that can be varied over seven orders of magnitude. It can be fabricated in a variety of shapes, sizes, and densities to meet the property requirements of specific applications.

CFOAM® is applicable to a broad spectrum of commercial, defense, and aerospace markets. It is an enabling technology for a host of next-generation material systems and components - replacing those currently based on more conventional materials such as balsa wood, intumescent mats, polymer matrices, metallic honeycombs, ceramic fibrous insulation, ceramic tile, Kevlar-based structures, polystyrene, plastics, fiberglass, rubber, and various metals.

Carbon foams are currently being developed for a variety of uses including fire-resistant ship decking and bulkheads, noise and impact mitigation for aircraft, structural panel and firewalls for vehicular armor, modular construction, and as part of spacecraft thermal management systems.

These foams will not off-gas at elevated temperatures and will not support ignition. Unlike those of most metals and ceramics, CFOAM®'s mechanical properties do not deteriorate with increased temperature if protected from oxidation, making carbon foams an attractive thermal protection material. Carbon foams are also tolerant to impact damage and can be repaired in-place using carbonaceous adhesives. CFOAM® can be integrated easily with dissimilar materials such as metals or polymer matrix composites (PMCs).

CFOAM® is a domestically produced material offering advantages such as low cost, enhanced structural properties, fire resistance, radar cross-section, corrosion susceptibility, and low weight.
