Carbon fiber reinforced bionic pearl layer ceramic matrix composite material and preparation method thereof
The invention belongs to the technical field of material synthesis and processing, and particularly relates to a carbon fiber reinforced bionic pearl layer ceramic matrix composite material and a preparation method thereof. The preparation method comprises the following steps: drawing a three-dimensional model of the pearl layer bionic ceramic bracket, carrying out reductive photopolymerization 3D printing to obtain an Al2O3 green body, separating a supporting structure from the Al2O3 green body, and sequentially carrying out cleaning, uncured slurry cleaning, ultrasonic cleaning, curing and drying on the Al2O3 green body to obtain a fully treated Al2O3 green body; degreasing and sintering the sufficiently treated Al2O3 green body to obtain the pearl layer bionic ceramic bracket; and performing filling treatment on the nacreous layer bionic ceramic bracket by using a carbon fiber epoxy resin filler to obtain the carbon fiber reinforced bionic nacreous layer ceramic-based composite material. The pearl layer bionic ceramic support is obtained through the reduction photopolymerization 3D printing technology, cracks can be deflected and retarded in the fracture process by filling the carbon fiber reinforced epoxy resin filler, and therefore the toughness of the composite material is improved.
本发明属于材料合成与加工技术领域，具体涉及一种碳纤维增强仿生珍珠层陶瓷基复合材料及其制备方法。制备方法包括：绘制珍珠层仿生陶瓷支架的三维模型并进行还原光聚合3D打印得到Al2O3生坯，从Al2O3生坯分离出支撑结构，依次对Al2O3生坯进行清洗、清理未固化浆料、超声清洗、固化和干燥，得到经充分处理的Al2O3生坯；将经充分处理的Al2O3生坯进行脱脂和烧结，获得珍珠层仿生陶瓷支架；使用碳纤维环氧树脂填充剂对珍珠层仿生陶瓷支架进行填充处理，获得碳纤维增强仿生珍珠层陶瓷基复合材料。本发明利用还原光聚合3D打印技术得到珍珠层仿生陶瓷支架，通过填充碳纤维增强的环氧树脂填充剂，在断裂过程可以使裂纹发生偏转与阻滞，从而增加复合材料的韧性。
