Material distribution method for preparing ceramic-based composite material by reactive infiltration method and application thereof
The invention relates to a material distribution method for preparing a ceramic-based composite material by a reactive infiltration method and application thereof. The method comprises the following steps: uniformly mixing epoxy resin and phenolic resin by using a solvent to obtain an epoxy phenolic resin solution; mixing the epoxy phenolic resin solution with an infiltration raw material, and kneading into raw material mud; smearing the raw material mud on the inner surface and/or the outer surface of the C/C composite material and compacting the material to obtain a coated raw material mud component; embedding carbon fibers into the surface layer of the coating raw material mud component to form a network structure, and coating the coating raw material mud component with the network structure to obtain a to-be-infiltrated component; and sequentially carrying out pre-curing treatment, high-temperature treatment before infiltration and high-temperature infiltration reaction on the to-be-infiltrated component to obtain the ceramic-based composite material. The reactive infiltration material distribution method is controllable in process, easy and convenient to operate, uniform in infiltration raw material distribution, stable in reaction and capable of enabling infiltration raw materials to be tightly attached to the C/C composite material. The method is suitable for preparing the large-size ceramic matrix composite material with the complex molded surface.
本发明涉及一种反应熔渗法制备陶瓷基复合材料的布料方法及其应用。所述方法：用溶剂将环氧树脂和酚醛树脂混合均匀，得到环氧‑酚醛树脂溶液；将环氧‑酚醛树脂溶液与熔渗原料混合后捏合成原料泥；将原料泥涂抹在C/C复合材料的内表面和/或外表面并压实，得到涂覆原料泥构件；在涂覆原料泥构件的表层埋入碳纤维形成网络结构包覆在所述涂覆原料泥构件上，得到待熔渗构件；将所述待熔渗构件依次进行预固化处理、熔渗前高温处理和高温熔渗反应，得到陶瓷基复合材料。本发明是一种工艺可控、操作简便、熔渗原料分布均匀、反应稳定、能够使得熔渗原料与C/C复合材料贴合紧密的一种反应熔渗布料方法，适宜制备大尺寸复杂型面陶瓷基复合材料。
