Carbon-carbon composite material as well as preparation process and application thereof
The invention belongs to the technical field of parts, and particularly relates to a carbon-carbon composite material as well as a preparation process and application thereof. The prepared carbon-carbon composite material comprises the following components in percentage by mass: 20%-36% of carbon fibers, 28%-45% of vapor deposition formed carbon and 26%-48% of impregnation formed carbon. The preparation process of the carbon-carbon composite material comprises the following steps of: preparing a prefabricated body, preparing an impregnant raw material and carrying out multi-stage densificationreaction. The carbon-carbon composite material disclosed by the invention can keep normal-temperature mechanical properties, thermophysical properties and frictional wear properties in high-temperature and ultra-high-temperature environments, and has relatively good application prospects and market prospects. The preparation method disclosed by the invention is high in economic benefit and reduces the cost by 50%, and the carbon-carbon composite material disclosed by the invention can be produced on a large scale.
本发明属于零部件技术领域，具体涉及一种碳碳复合材料及其制备工艺和应用。本发明的制备的碳碳复合材料，按照质量计包括碳纤维20％—36％、气相沉积成碳28％—45％、浸渍成碳26％—48％；本发明碳碳复合材料的制备工艺，包括预制体制备、浸渍剂原料制备、多级增密反应。本发明的碳碳复合材料能在高温和超高温环境中保持常温状态下的力学性能、热物性能和摩擦磨损性能，具有较好的应用前景与市场前景。本发明的制备方法经济效益强，成本低50％，可大批量生产本发明的碳碳复合材料。
