Method for manufacturing copper mesh modified carbon/carbon composite material for pantograph slide plate of electric locomotive
The invention discloses a method for manufacturing a copper mesh modified carbon/carbon composite material for a pantograph slide plate of an electric locomotive. The method comprises the following steps: (1) preparation of carbon fiber and copper mesh hybrid preform: sequentially laying a carbon fiber web and a continuous copper mesh having a copper wire diameter of 50-500mu m and a pore diameter of 150-500mu m in an overlapping manner for at least two times, and then introducing carbon fiber bundles from the direction vertical to the laying layer to form carbon fiber and copper mesh hybrid preform, wherein the tread density of the carbon fiber web is 50-100g/m<2>, and the density of the carbon fiber and copper mesh hybrid preform is 0.30-0.80g/cm<3>; and (2) carbon densification of the prefrom: leading the material density to be 1.60-2.20g/cm<3> by adopting a carbon/carbon composite material densification process. The copper mesh modified carbon/carbon composite material has the characteristics of low density, low abrasion, high strength, high conductivity and the like, and can be used for meeting the requirements of a high-speed electric locomotive and the like for slide conductive materials in China.
