carbon fiber/thermosetting resin matrix precursor modified by graphite powder heat treated at 1000 degrees c and at 3000 degrees c were prepared. the flexural strength and fracture pattern of the composites were observed. small addition (5-10 percent ) of graphite powder to matrix precursor was effective on the strength of both types of carbonized composites, and graphitized ones with non-surface-treated fiber but was not so effective on that of the graphitized composite with surface-treated carbon fiber. small addition of graphite powder gave ductility to the carbonized matrix and decreased interfacial gaps in the graphitized composite with non-surface treated fibers. however, a large amount of graphite powder addition was less effective, due to the matrix inhomogeneity
