Silver-plated carbon fiber-enhanced carbon-based pantograph sliding plate

Abstract

The invention discloses a silver-plated carbon fiber-enhanced carbon-based pantograph sliding plate. A preparation method of the silver-plated carbon fiber-enhanced carbon-based pantograph sliding plate comprises the steps that pretreating is conducted by taking carbon fiber cloth as a raw material, a chemical silver plating solution is added into the pretreated carbon fiber cloth, and a well-plated silver layer is obtained; the silver-plated carbon fiber cloth, a copper mesh, short-cut carbon fibers, modified phenolic resin, graphite, copper powder, butadiene-acrylonitrile rubber and the like form mixed materials, the mixed materials are subjected to compression molding treating, hot-press sintering and steeping re-pressing, and then the silver-plated carbon fiber-enhanced carbon sliding plate can be obtained. According to the silver-plated carbon fiber-enhanced carbon-based pantograph sliding plate, by adding enhancement bodies such as the silver-plated carbon fibers into the carbon-based sliding plate, the electrical conductivity and the heat conductivity of the sliding plate can be improved, the bonding property and the interface bonding strength between internal materials including the carbon fibers and other components of the sliding plate are improved, the self-lubricating property of the sliding plate is improved, the service performance of the pantograph sliding plate in a high speed railway is further enhanced, and the service life of the pantograph sliding plate is prolonged.

Description

technical field [0001] The invention relates to the technical field of pantograph slides for high-speed trains, and more particularly, to a carbon fiber-reinforced carbon-based pantograph slide. Background technique [0002] Electric locomotive pantograph slides, as the key current-collecting components for high-speed trains to obtain energy, occupy an important part of the "throat". Its good service performance is an important condition to ensure the safe and reliable operation of high-speed trains. With the continuous increase of train speed and current transmission density, the shock vibration of the pantograph-catenary system is intensified, and pantograph-catenary arcs occur frequently, resulting in abnormal wear or even fracture of the slide plate material, resulting in train failure. At present, the research and development of high-performance pantograph slides with high conductivity, strong wear resistance and self-lubrication has become a very important research top...

Problems solved by technology

However, its impact resistance is still poor, and the process is complicated and the production cost is high

[0004] There is also a carbon fiber-reinforced carbon-based pantograph slide. Due to poor wettability between carbon fiber and copper, and the two do not dissolve or react at high temperatures, there is a problem of poor adhesion.
