Carbon copper fiber pantograph carbon slide plate composite material and preparation method thereof
The invention relates to the technical field of electric vehicle equipment preparation, in particular to a carbon-copper fiber pantograph carbon slide plate composite material and a preparation method thereof, and the preparation method comprises the following steps: step 1, preparing a carbon-copper fiber preform; step 2, preparing resin slurry; step 3, resin impregnation; step 4, performing mould pressing carbonization forming; 5, chemical vapor deposition densification is carried out; and 6, performing high-temperature heat treatment to obtain the final pantograph carbon slide plate composite material. The short carbon fibers and the copper wires are carded to form the net tire, and then the net tire is needled to form the prefabricated body, so that the defect that a traditional carbon fiber structure pantograph material has obvious anisotropy is effectively overcome; the catalyzable graphite powder is added into the resin to prepare the resin slurry, so that the graphitization degree of resin carbon and subsequently deposited carbon can be effectively improved, and the resistivity of the whole pantograph material is further reduced; and a compression molding mode is adopted, so that the overall mechanical property and conductivity of the material are obviously improved.
本发明涉及技术领域电力车辆设备制备，具体是一种碳铜纤维受电弓碳滑板复合材料及其制备方法，包括以下步骤：步骤1、碳铜纤维预制体制备；步骤2、树脂浆料制备；步骤3、树脂浸渍；步骤4、模压碳化成型；步骤5、化学气相沉积增密；步骤6、高温热处理得到最终的受电弓碳滑板复合材料。本发明通过将短切碳纤维和铜丝梳理形成网胎，然后针刺形成预制体，有效的避免了传统碳纤维结构受电弓材料具有明显的各向异性的缺点；通过在树脂中加入可催化石墨粉末制备树脂浆料，可有效的提高树脂碳以及后续沉积碳的可石墨化程度，进一步降低整体受电弓材料的电阻率；采用模压成型的方式，对材料整体的力学性能和导电性能具有明显的提升作用。
