Low-cost carbon/graphite throat liner material and preparation method thereof
The invention provides a low-cost carbon/graphite throat liner material and a preparation method thereof, and aims to solve the problems of long preparation period and high cost of an existing C/C composite material throat liner. The invention discloses a preparation method of a low-cost carbon/graphite throat liner material. The preparation method comprises the following steps: S1, preparing a carbon fiber skeleton; s2, graphite powder and asphalt mixture filling-carbonization: graphite powder and asphalt are uniformly mixed, a carbon fiber skeleton is filled with the mixture, vibration treatment is performed to enable the mixture to be compacted, and then the mixture is put into a carbonization furnace to be subjected to carbonization treatment; s3, asphalt impregnation-carbonization: impregnating the blank obtained in the S2 with asphalt, and performing carbonization treatment; s4, graphitization treatment is conducted, specifically, the blank obtained in the S3 is subjected to graphitization treatment, and the treatment temperature is 2500 DEG C; and S5, repeating the steps S3 and S4 for many times to obtain the composite material with the density of 1.85 g/cm < 3 > or above. Compared with a C/C composite material preparation method, the preparation method has the characteristics of rapidness and low cost, and has the characteristic of high strength compared with a graphite material.
本发明提供一种低成本碳/石墨喉衬材料及其制备方法，以解决现有的C/C复合材料喉衬制备周期长、成本高的问题。一种低成本碳/石墨喉衬材料制备方法，步骤为S1：制备碳纤维骨架；S2：石墨粉沥青混合料填充‑碳化，将石墨粉和沥青混合均匀，填入碳纤维骨架内，并进行振荡处理使其填实，再放入碳化炉内进行碳化处理；S3：沥青浸渍‑碳化，对S2获得的毛坯浸渍沥青，并进行碳化处理；S4：石墨化处理，对S3获得毛坯进行石墨化处理，处理温度为2500℃；S5：通过重复S3和S4过程次数获得密度为1.85g/cm3以上复合材料。本发明相比C/C复合材料制备方法具有快速低成本的特点，相比石墨材料具有强度高的特点。
