In-situ growth carbon nanotube reinforced carbon fiber composite material carbon slide strip
The invention relates to an in-situ growth carbon nanotube reinforced carbon fiber composite material carbon sliding strip, and belongs to the technical field of preparation of materials for electric locomotives. In the carbon fiber composite material, on the premise that a catalyst is not adopted, carbon nanotubes and carbon particles grow in situ inside and outside the coated carbon fiber needled integral felt, the distribution of the carbon nanotubes and the carbon particles is controlled, rapid carbonization/graphitization is realized in combination with asphalt impregnation-carbonization, the graphitization degree can reach 93% after high-temperature graphitization treatment, and the carbon fiber needled integral felt has good mechanical properties. And the preparation process is simple, and the product has excellent mechanical, conductive and friction properties, and is suitable for large-scale industrial application and production.
本发明涉及一种原位生长碳纳米管增强碳纤维复合材料碳滑条，属于电力机车用材料制备技术领域。本发明在碳纤维复合材料内部，在不采用催化剂的前提下，在包覆炭纤维针刺整体毡内部、外部原位生长了碳纳米管和碳颗粒并控制二者分布，结合沥青浸渍‑碳化实现快速碳化/石墨化，在高温石墨化处理后石墨化度即可达到93％，且制备工艺简单，产品力学、导电和摩擦性能优越，适于大规模的产业化应用和生产。
