把贝壳珍珠层的韧化机制和结构机理应用于陶瓷基复合材料的仿生设计中，制备出Ａｌ２Ｏ３／环氧树脂及Ａｌ２Ｏ３／芳纶纤维增强环氧树脂叠层仿珍珠层复合材料三点弯曲试验表明、与单相Ａｌ２Ｏ３相比，Ａｌ２Ｏ３／环氧树脂复合材料的断裂功提高２５％，而Ａｌ２Ｏ３／芳纶纤维增强环氧树脂的断裂功提高８０倍Ａｌ２Ｏ３／环氧树脂复合材料的断裂形貌与珍珠层相似，裂缝曲折扩展；而Ａｌ２Ｏ３／芳纶纤维增强环氧树脂复合材料除具有主裂缝曲折扩展特征外．Ａｌ２Ｏ３层还发生多裂缝断裂本试验中的材料结构设计思想为陶瓷的韧化提供了一条新途径
The toughening mechanism and structural mechanism of the nacre shell were applied to the bionics design of ceramic matrix composites to prepare the three point bending test of Al2O3 / epoxy resin and Al2O3 / aramid fiber reinforced epoxy resin laminated imitation nacre layer composite The results show that the fracture work of Al2O3 / epoxy composites is 25% higher than that of single phase Al2O3, while the fracture work of Al2O3 / aramid fiber reinforced epoxy resin is 80 times higher than that of Al2O3 / epoxy composites Similar to the nacre, the cracks propagate zigzag; while the Al2O3 / aramid fiber reinforced epoxy composites have the main crack zigzag expansion characteristics. The multi-crack fracture occurred in the Al2O3 layer. The material structure design in this experiment provides a new way for the toughening of ceramics
