โœฆ Synopsis

Carbon fibers grown by pyrolysis of natural gas were heat-treated at temperatures ranging from 1400 to 3OOO"C, and characterized by X-ray diffraction. Their electrical resistivity is reported for temperatures between 10 and 370 K, and explained for heat treatment above 2200ยฐC using a simple graphitic band model. Filaments heat-treated at lower temperatures and as-grown fibers show a resistivity with a small temperature dependence.

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 densitie

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
