carbon fiber/carbon composites were prepared with a thermosetting resin-derived carbon matrix and two groups of carbon fibers (i. e. , surface treated and non-surface treated) with and without sizing treatment. these composites were heat treated at 1000 $degree$ c and 3000 $degree$ c. the composite with surface treated carbon fibers heat treated at 1000 $degree$ c showed low strength and a catastrophic fracture pattern, whereas those heat treated at 3000 $degree$ c showed a pseudo-plastic fracture pattern. however, the behavior was just the opposite in the composite with non-surface treated carbon fibers. graphitization of composites with two series of carbon fibers showed a different matrix microstructure. composites with surface treated fibers showed a columnarlike carbon matrix whereas those made with non-surface treated fibers possessed a lamellar type carbon matrix oriented around the carbon fibers (edited author abstract) 11 refs
