Method for rapidly compacting carbon-carbon composite material
The invention discloses a method for rapidly compacting a carbon-carbon composite material, which comprises the following steps: carrying out heat treatment on a carbon-carbon green body to obtain a carbon-carbon porous body, soaking the carbon-carbon porous body in a phosphoric acid aqueous solution, after soaking, obtaining a carbon-carbon porous body subjected to interface pretreatment, placing the carbon-carbon porous body subjected to interface pretreatment in an impregnation tank of an impregnation device, vacuumizing, and drying to obtain the carbon-carbon composite material. Then, sucking the impregnant into an impregnation tank, and carrying out pressure impregnation, curing, carbonization and graphitization; repeating pressure impregnation, curing, carbonization and graphitization until a compact carbon-carbon composite material is obtained; the impregnant comprises furfuryl ketone resin, phosphoric acid and zinc chloride. The impregnation frequency of the carbon-carbon composite material can be reduced by 10%-40%, the overall mechanical property is improved by 5%-20%, and the service life of the resin can be prolonged by 50%-100%.
本发明公开了一种碳碳复合材料快速致密的方法，将碳碳坯体进行热处理，获得碳碳多孔体，将碳碳多孔体浸泡于磷酸水溶液中，浸泡完成后，获得经界面预处理的碳碳多孔体，将经界面预处理的碳碳多孔体置于浸渍装置的浸渍罐中，抽真空，然后将浸渍剂吸入浸渍罐，加压浸渍、固化、炭化、石墨化；重复加压浸渍‑固化‑炭化‑石墨化，直至获得致密的碳碳复合材料；所述浸渍剂包含糠酮树脂、磷酸、氯化锌。本发明可以使碳碳复合材料的浸渍次数可减少10％～40％，力学性能整体提高5％～20％，树脂使用寿命可延长50％～100％。
