Composite material for high-conductivity pantograph slide plate for high-speed rail and preparation method of composite material
The invention discloses a composite material for a high-conductivity pantograph slide plate for a high-speed rail and a preparation method of the composite material. The composite material is prepared by the following steps: densifying a three-dimensional woven preform to the density of 2.1-2.7 g/cm < 3 > by chemical vapor infiltration (CVI) and melt infiltration (RMI) methods; the preparation method comprises the following steps: preparing the carbon fibers into a three-dimensional braided preform, performing degumming treatment on the preform, preparing a low-density carbon fiber reinforced matrix carbon green body by adopting a CVI method, and then performing high-temperature graphitization treatment and RMI to prepare the required composite material for the carbon-copper dual-base pantograph slide plate. The prepared composite material for the carbon-copper dual-element-based pantograph slide plate has the advantages of being low in preparation cost, good in conductivity, high in mechanical property, excellent in current-receiving wear resistance and arc erosion resistance, and suitable for industrial production.
