Preparation method of novel carbon/carbon-copper composite material sliding strip
The invention provides a preparation method of a novel carbon/carbon-copper composite material sliding strip. The preparation method is characterized by comprising the following steps that S1, 0-degree weftless carbon cloth, a carbon fiber web, 90-degree weftless carbon cloth and a carbon fiber web are sequentially and circularly superposed for multiple times, and compounding is conducted in a needling manner, so that a prefabricated body is prepared; S2, the prefabricated body prepared in the step S1 is subjected to chemical vapor deposition pyrolytic carbon treatment to prepare a carbon/carbon composite material; S3, the carbon/carbon composite material prepared in the step S2 is subjected to high-temperature treatment; S4, the carbon/carbon composite material subjected to high-temperature treatment in the step S3 is machined to be in a preset sliding strip size, and a prefabricated sliding strip is prepared; and S5, the prefabricated sliding strip in the step S4 is subjected to vacuumizing treatment, then copper or copper alloy is subjected to pressure impregnation, and the carbon/carbon-copper composite material sliding strip is prepared. According to the method, the process iseasy to operate, and the prepared sliding strip has good impact resistance, small resistivity, excellent performance and good application and popularization value.
一种新型炭/炭‑铜复合材料滑条的制备方法，其特征在于，包括以下步骤：S1：将0°无纬炭布、炭纤维网胎、90°无纬炭布、炭纤维网胎依次循环叠加多次并通过针刺的方式复合，制得预制体；S2：对步骤S1制得的预制体进行化学气相沉积热解炭处理，制得炭/炭复合材料；S3：对步骤S2中的炭/炭复合材料进行高温处理；S4：对经步骤S3高温处理的炭/炭复合材料进行机械加工至预设的滑条尺寸，制得预制滑条；S5：将步骤S4的预制滑条进行抽真空处理，然后加压浸渍铜或铜合金，制得炭/炭‑铜复合材料滑条。本发明所述工艺操作简单，制备出的滑条具有较好的抗冲击性能以及较小的电阻率，性能优良，具有很好的推广应用价值。
