摘　　要：高空隙率生物陶瓷支架是骨组织工程中的研究热点,但其陶瓷本身的脆性和高空隙率带来的强度差等问题限制了其在临床中的应用。随着陶瓷工艺的进步,一些增强补韧的方法应运而生,主要包括纤维增韧、晶须增韧、颗粒增韧、复合增韧、自增韧等。这些方法使陶瓷材料的强度和韧性有了较大提高。现就各种方法的相关机制进行论述,探讨陶瓷材料增韧补强技术的研究现状,并对其今后的发展前景进行展望。High porosity biological ceramic scaffold is a research hotspot in bone tissue engineering,however the clinical application is hampered by the fragility and low intensity of porous composite.Several methods of reinforcing and toughening porous composite such as fiber toughening,particle toughening,combination toughening and self-toughening are proposed with the development of ceramics.The related toughening effects and mechanisms of each method are discussed here,and the research status and direction are pointed out.
