Preparation method of high-temperature-resistant, radiation-resistant and stealth multifunctional integrated ceramic-based composite material
The invention relates to a preparation method of a high-temperature-resistant, radiation-resistant and stealth multifunctional integrated ceramic matrix composite material. The preparation method comprises the following steps: a, preparing coating slurry containing functional filling particles by ball milling and preparing silicon carbide (SiC) prefabricated cloth by a chemical vapor infiltration (CVI) process; b, uniformly coating the surface of the SiC prefabricated cloth with the mixed slurry, and neatly stacking and fixing; and c, depositing a silicon nitride (Si3N4) matrix on the laminated and fixed prefabricated body by a CVI (Chemical Vapor Infiltration) process for densifying. According to the preparation method provided by the invention, the integration of a high-temperature-resistant, radiation-resistant and stealth multifunctional structure of the ceramic-based composite material is realized, the mechanical property of the ceramic-based radiation shielding material in a high-temperature environment is enhanced, and the multifunctionality and high-temperature environment durability of the ceramic-based composite material are improved; meanwhile, the application range of the ceramic-based composite material is expanded.
本发明涉及一种耐高温‑抗辐照‑隐身多功能一体化陶瓷基复合材料的制备方法，包括以下步骤：a.球磨制备包含功能填充颗粒的涂敷浆料和化学气相渗透(CVI)工艺制备碳化硅(SiC)预制布；b.将混合浆料均匀涂敷于SiC预制布表面并堆叠整齐固定；c.将叠层固定好的预制体进行CVI工艺沉积氮化硅(Si3N4)基体进行致密化。本发明提供的制备方法实现了陶瓷基复合材料的耐高温‑抗辐照‑隐身多功能结构一体化，加强了陶瓷基辐射屏蔽材料在高温环境中的力学性能，提高了陶瓷基复合材料的多功能性和高温环境耐久性，同时拓展了陶瓷基复合材料的应用范围。
