โœฆ Synopsis

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 earlier high-strain, static-pulling methods. Although the amplitude of vibrational response for these fibers is linear in the driving force, the shape of the frequency response deviates from Lorentzian as the amplitude increases. This behavior has not been previously reported in other materials. Possible explanations based on the fibers' microstructure are discussed.

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
