Typical microcellular Carbon foam Unidirectional fiber reinforced Carbon foam Wovenfabric reinforced Carbon foam

Microcellular carbon graphitic foam is a new foamed material which contains open-celled microcellular/carbon graphitic network created from carbon fiber precursors. Our foaming process aligns the graphene planes along each ligament axis. The morphology of the ligaments resembles that of carbon fibers, and hence, their mechanical characteristics are similar to those of the fibers’. The foams can be used as net shaped preforms for reinforcement of structural composites, sandwich core, and structural components for high temperature applications. Microcellular carbon/carbon composites are carbon fibers reinforced carbon matrix that have a microcellular morphology. The fibers can be chopped, unidirectional or woven. Wright Materials Research Co. (WMR) has developed two proprietary foaming and post processing technique for this class of ultra-lightweight carbon material. Sandwich structures with microcellular carbon/graphitic foam core Features of WMR's C & C/C Foaming Technique Single-Step Process Environmentally friendly Scalable to very large parts Physical and functional properties of parts can be tailored by WMR’s processing technique Foam density can be controlled from a few pcf to over 70 pcf Starting materials include isotropic pitch, mesophase pitch, PAN, and various polymers WMR’s agile foaming technique offers custom made ability
