| Abstract: | This paper researched the effect of the length and quantity of graphite on mechanical properties. The results show that the properties are excellent,the smooth finish is high, when the quantity of graphite is less than 15% and the length is within 50～200 μm.According to experimental data, the regressive equation is established by regression analysis. |
