| Research Abstract |
Mesophase pitch has been successfully prepared at very highly yield from aromatic hydroearbons with low contaminant levels using HF/BF_3 as a catalyst. The derived carbon fiber is expected to be of high performance and to be produced at reasonable cost. The synthesis, structure, and properties of the mesophase pitchs, which are strongly dependent upon the starting aromatic hydrocarbons and preparation conditions, will be described. The spinning process can control the shape and texture of the fiber, both of which are intimately related to performance. Fibers with a flat cross section, as thin as 1.5 micrometer, and round fibers with random texture can be produced when the spinning nozzle and the mesophase pitch are properly selected. Acceptable compression strength has been obtained with the ranbdomtexture in the round realized by slow heating during stabilization. Some other applications of mesophase pitch can be addressed.
