| Abstract: | The carbon fiber coating with SiO2 film was formed by sol-gel. The new process adopted the solution of TEOS with organic additives,and went through two-step hydrolysis procedure,polycondensing,drying and sintering. The results show that the SiO2 film improves the wetting property between fiber and alloy. And C/Mg composite is prepared under a low pressure infiltration and the damping property is improved. |
