Preparation method of oxide continuous filament reinforced oxide ceramic-based composite material
The invention relates to a preparation method of an oxide continuous filament reinforced oxide ceramic-based composite material, which comprises the following steps: immersing a pretreated oxide filament two-dimensional braided fabric in prepared aluminum phosphate interface phase slurry, taking out, vertically hanging, airing, and presintering; preparing uniform and stable water-based oxide ceramic slurry by adopting a multi-stage reverse stirring process; an ultrasonic-assisted high-pressure coating process is adopted, and a composite material frame is obtained; finally, the prepared homogeneous transparent oxide sol is used for carrying out 2-3 dipping compensation and repair on microdefects in the composite material frame, and the oxide continuous filament reinforced oxide ceramic-based composite material with low porosity and few defects is obtained through a drying-calcining process. Compared with the prior art, the mechanical property of the composite material is effectively improved, and the composite material is short in preparation process, simple in process and high in porosity.
本发明涉及一种氧化物连续长丝增强氧化物陶瓷基复合材料的制备方法，其中包括：将预处理后的氧化物长丝二维编织物浸于制备的磷酸铝界面相浆料中，随后取出垂直悬挂晾干进行预烧结处理；采用多级逆向搅拌工艺，制备均匀稳定的水基氧化物陶瓷浆料；采用超声波辅助高压涂覆工艺，获得复合材料框架；最后利用制备的均相透明氧化物溶胶对复合材料框架中的微缺陷进行2～3浸渍弥补修复，经干燥‑煅烧工艺获得孔隙率低、缺陷少的氧化物连续长丝增强氧化物陶瓷基复合材料。与现有技术相比，本发明有效提升了复合材料的力学性能，且复合材料制备流程短、工艺简单、孔隙率高。
