Problems solved by technology

However, this kind of slide plate has complex process, high cost, large wear and tear on the catenary wire, and poor impact resistance.
Chinese invention patent CN1178745A discloses a carbon-carbon composite material pantograph slide plate, using carbon fiber reinforced carbon-based composite material to manufacture electric locomotive pantograph slide plate, using copper-plated carbon powder as the matrix material, and short carbon fiber as the reinforcing agent , and use thermosetting resin as binder, wet mixing or dry mixing method, fully mix the raw materials, and then perform cold pressing and hot pressing to make the thermosetting resin solidify and form. This pantograph slide material has good friction and wear properties , the degree of wear to the contact wire is small, but the mechanical strength is not high

Abstract

A carbon / carbon slide block of current collector for electric locomotive is prepared through providing prefabricated body made of punched non-weft fabric with tridirectional structure, depositing pyrolytic carbon by CVD, compacting by resin dipping-charring process several times, and machining.

Description

technical field [0001] The invention belongs to the technical field of transportation vehicle accessories, and in particular relates to a method for preparing a carbon / carbon pantograph slide plate for an electric locomotive. Background technique [0002] Skateboards are mainly divided into metal-based skateboards and carbon-based skateboards according to their materials. Metal-based skateboards include pure metal skateboards and powder metallurgy skateboards; carbon-based skateboards include pure carbon skateboards and metal-infiltrated carbon skateboards. Among them, due to the similar material and strong affinity with the contact wire, the pure metal slide plate wears the contact wire very seriously, and has been eliminated at present. [0003] The development of railways toward electrification and high-speed is to meet the needs of national economic and social development. The pantograph-catenary system of an electrified railway is one of the key links that determine th...
