Abstract : This report contains results and discussions related to the investigation of the materials and process parameters associated with the development of the mesophase- graphite process. Three starting materials are investigated as precursors for preparing mesophase graphite. The conditions for converting these precursors to mesophase and subsequent processing parameters are discussed. Graphites produced from each of these materials are characterized as to strength, density, and coefficient of thermal expansion. Additional work with two of the three precursors is conducted in an effort to determine the feasibility of molding mesophase to shape and using mesophase as a matrix for carbon/graphite fibers.
