Carbon Honeycomb

For the next level of mechanical and thermal performance, Ultracor developed carbon fiber honeycomb. Ultracor has manufactured carbon structural honeycomb from both pitch and PAN precursor materials.

Ultracor carbon fiber honeycomb is used in advanced satellite antennas and instrument benches to achieve the thermal stability of near zero CTE.  Our carbon/epoxy honeycomb provides an unparalleled mechanical strength when compared to other materials.
