✦ Synopsis

Vapor-grown carbon-fiber (VGCF) reinforced carbon (VGCF-C) composites were studied for thermal and physical properties.

Effect of fiber volume fraction and final density of composite on thermal conductivity was investigated. The fiber volume fractions range from 25 v/o to 36% and the final densities range from 1.15 g/cc to 1.59 g/cc. A composite with a fiber volume fraction of 36% and a density of 1.59 g/cc was found to exhibit a room-temperature thermal conductivity of 564 W/m-K after being heat treated at 2800°C. This value of thermal conductivity was attributed to the highly graphitic nature of reinforcing VGCF mats. The room-temperature thermal conductivity of VGCF mat used as reinforcement was estimated to be 1760 W/m-K.

The elastic properties of individual vapor-grown carbon fibers have been studied via the lowstrain, vibrating-reed technique. The average Young's modulus is found to be 680 GPa, with some indication that the intrinsic modulus of CVD carbon may be much higher. This value exceeds those found by earli

Carbon fibers were grown on alumina substrates by vapor phase decomposition of benzene in the presence of hydrogen in a tubular reactor. The effect of lengthening duration and temperature on the average fiber length was studied at two different benzene concentrations (13.2 and 18.6 mol%). In the tem
