| Abstract: | Nano Al 2O 3modified polytetrafluoroethylene(PTFE) was made by process of pressing and sintering,and the mechanical properties of the modified PTFE were studied by means of test The results showed that nano Al 2O 3had important effect on the improvement of the reinforcing of PTFE,the use of nano Al 2O 3increased the tensile strength and hardness of PTFE,and the friction coefficient of PTFE was decreased,while the elongation at break of PTFE decreased at the same time So the content of nano Al 2O 3should be controlled according to the requirement for the application of the modified PTFE |
