Abstract

Previous work at Clemson University has shown that ribbon-shaped mesophase pitch-based carbon fibers graphitized at only 2400°C can develop thermal conductivities comparable with those of commercial round-shaped pitch-based carbon fibers graphitized at temperatures above 3000°C. The thermal and electronic transport properties (i.e. thermal conductivity and electrical resistivity) of ribbon-shaped carbon fibers produced at Clemson University are being studied. In addition, the structure of these fibers is being analyzed by electron microscopy and X-ray diffraction techniques. This paper will discuss the relationships between processing conditions, fiber structure and fiber properties.

Funding

The work was supported primarily by the ERC Program of the National Science Foundation under Award Number EEC-9731680. A portion of the research was funded by the Office of Naval Research project on high thermal conductivity carbon fibers (Contract No. N0014-95-1-1345). The authors would also like to thank Drs Chris Levan and Girish Deshpande for permitting us access to the Angstrom's apparatus at BP-Amoco and Prof. Jean-Paul Issi and Dr Bernard Nysten for allowing us to use the thermal potentiometer at the University of Louvain-la-Neuve in Belgium. Finally, thanks are also due to Dr David Anderson of the University of Dayton Research Institute for his expertise and assistance in obtaining the single-filament X-ray data and to the National Synchrotron Light Source at the Brookhaven National Laboratory for access to the high energy beam used in these experiments.
