Preparation method of zirconium oxide and continuous carbon fiber co-reinforced quartz ceramic composite material
The invention discloses a preparation method of a zirconia and continuous carbon fiber co-reinforced quartz ceramic composite material, which comprises the following steps: soaking continuous carbon fiber in acetone, cleaning with distilled water, and drying in a drying oven; completely immersing the dried continuous carbon fibers into pure methanol, ultrasonically stirring, and putting the separated continuous carbon fibers into a drying oven until the continuous carbon fibers are completely dried; mixing fused quartz powder, zirconium oxide powder and a dispersing agent in ionized water, and carrying out ball milling to obtain an impregnated material; impregnating the pretreated continuous carbon fibers into the impregnated material to obtain an impregnated and molded composite material; and stacking the material in a graphite mold, and carrying out hot pressed sintering in a nitrogen atmosphere to obtain the composite material. The method is simple in process, short in forming time and low in cost, the interface bonding strength of the carbon fiber and the quartz ceramic matrix in the prepared composite material and the bending strength perpendicular to the fiber direction can be effectively improved, and the obtained composite material can have good high-temperature stability and self-healing performance.
本发明公开了一种氧化锆与连续碳纤维共增强石英陶瓷复合材料的制备方法，包括以下步骤：将连续碳纤维浸泡在丙酮中，用蒸馏水清洗后在烘箱中干燥；将干燥后的连续碳纤维完全浸入纯甲醇中，超声搅拌后，将分离出的连续碳纤维放入烘箱中直到完全干燥；将熔融石英粉、氧化锆粉、分散剂在离子水中混合进行球磨制得浸渍料；将经过预处理后的连续碳纤维浸渍到浸渍料中得到浸渍成型后的复合材料；将材料堆放在石墨模具中，在氮气气氛下热压烧结得到复合材料。该方法工艺简单、成型时间短、成本低，能有效增加所制备得到的复合材料中碳纤维和石英陶瓷基质的界面结合强度和垂直于纤维方向的弯曲强度，所得到的复合材料可具有良好的高温稳定性和自愈合性能。
