Rapid preparation method of carbide superhigh-temperature ceramic-SiC gradient and uniformly modified C/C composite material
The invention belongs to the technical field of preparation of matrix modified C/C composite materials, and particularly relates to a rapid preparation method of a carbide superhigh temperature ceramic-SiC gradient and uniformly modified C/C composite material. The SPS technology and the matrix modified C/C composite material preparation technology are combined to achieve the purpose of rapid preparation. The method has low damage to fibers, the ceramic phase in the prepared material is tightly combined with the matrix, and the laid powder can fully permeate into the matrix, so that the caking waste phenomenon of the accumulated powder outside the sample is avoided; meanwhile, the gradient and uniform modified C/C composite material can be prepared by controlling the total amount of powder laid on the upper portion and the lower portion of the base body, the SPS pressure and the reaction temperature to cooperatively control the penetration depth of the powder, and controllability is high. The method is short in preparation period, the modified C/C composite material can be prepared within 1-2 hours, and the method is suitable for large-scale and low-cost preparation of the carbon-based/ceramic-based composite material.
本发明属于基体改性C/C复合材料制备技术领域，具体为一种碳化物超高温陶瓷‑SiC梯度及均匀改性C/C复合材料的快速制备方法。本发明将SPS技术与基体改性C/C复合材料制备技术相结合达到快速制备的目的。本方法对纤维损伤低，所制备材料内部陶瓷相与基体结合紧密，铺设粉料可以充分渗入基体，避免了样品外部堆积粉料的结块浪费现象，同时可以通过控制基体上下铺设的粉料总量、SPS压力和反应温度协同控制粉料渗入深度以制备梯度及均匀改性C/C复合材料，可控性强。本方法制备周期短，可在1‑2小时内制备出改性C/C复合材料，适用于碳基/陶瓷基复合材料的大规模及低成本制备。
