    The effect of bronze sintered friction materials on frictional and mechanical properties is studied with the content(8-18 wt,%) and shapes (flake and friegular) of graphite that is used as solid lubricants to meet diverse characteristics such as low coefficient of friction, low wear rate and high bending strength The content and shapes of graphite are optimized by statistical experiments Friction test was carried out mea녁e friction coefficient, temperature dependence and wear rate. As a result of experiments, the density, hardness and bending strength with a shape of flake graphite are lower and decrease rapidly than that of Irregular, as the content of graphite increases up to 18 wt% Aftei friction test, coefficient of friction is 03 -0 4 and wear rate is 032~2 98×10-7 cm²/kgㆍm When the content of graphite increases, coefficient of friction increases In a shape of flake graphite and decreases in a shape of Irregular graphite
