The direct measurements of the principal thermal expansion coefficients were carried out for the specimens of pyrolytic graphite at temperatures between 50 and 55O"C, using an apparatus with high sensitivity. Resolving power of the apparatus was f 100 A. The c-axis thermal expansion coefficient was
Graphite crystal expansions were derived as a function of' temperature usmg the theoretical relationships of Riley; the resultant equations provide reasonable tits to the measured lattice expansion data over the temperature range 300-3000%

The electron microscope (both in the scanning and transmission modes) was used to examine the topography of both wet (60% HNOs, 118ยฐC) and dry oxidized (air, 700ยฐC) fibers as well as fracture surfaces of composites made with treated and untreated fibers.
