High-carbon SiCN precursor, impregnant, ceramic-based composite material and preparation method
The invention relates to a high-carbon SiCN precursor, an impregnant, a ceramic-based composite material and a preparation method, and belongs to the technical field of preparation of ceramic-based composite materials. Compared with the conventional SiCN ceramic, the high-carbon SiCN ceramic has a higher temperature-resistant grade, and the ceramic-based composite material developed by taking the high-carbon SiCN ceramic as a matrix has more excellent high-temperature mechanical properties. Through molecular structure and chemical synthesis design, a high-carbon SiCN precursor is developed, and the continuous fiber reinforced high-carbon SiCN ceramic-based composite material is prepared by taking the high-carbon SiCN precursor as an impregnant and adopting a liquid-phase impregnation process. The process is low in raw material cost, the liquid phase impregnation process is good in applicability, and the liquid phase impregnation process is suitable for being applied to development of bearing components under the high-temperature condition and has good application prospects.
本发明涉及一种高碳SiCN前驱体、浸渍剂、陶瓷基复合材料及制备方法，属于陶瓷基复合材料制备技术领域。高碳SiCN陶瓷相比于常规SiCN陶瓷具有更高的耐温等级，以高碳SiCN陶瓷为基体研制的陶瓷基复合材料则具有更优异的高温力学性能。通过分子结构与化学合成设计，研制出高碳SiCN前驱体，并以其为浸渍剂采用液相浸渍工艺制备连续纤维增强高碳SiCN陶瓷基复合材料。该工艺原材料成本低廉，液相浸渍工艺适用性良好，适合应用于高温条件下承载构件的研制，具有良好的应用前景。
