摘要:

碳納米管作為一維納米材料，具有重量輕及高強度、高韌性等優異力學性能，與工程結構陶瓷材料復合能夠強韌化陶瓷材料的力學性能，被認為是現代結構陶瓷復合材料理想增強體。本文綜合了近年來碳納米管增強陶瓷基復合材料在理論及實驗方面的研究結果的基礎上。側重介紹了碳納米管增強陶瓷基復合材料的強韌化機理研究，如細化晶粒增韌、短纖維增韌和碳納米管獨特的坍塌增韌、多壁碳納米管抽出增韌機制，以及采用剪切滯后理論模型對碳納米管與陶瓷基體的微觀界面結合的力學性能的模擬研究結果。并對國內外在碳納米管在陶瓷基體中的強韌化機理的實驗及模擬研究結果進行了綜合分析，總結了當前碳納米增強陶瓷復合材料研究的困境、存在的問題，并指出今后理論及實驗研究方向。

Abstract:

Carbon nanotube, as a one-dimension nanomaterial with a lightweight has excellent mechanical properties like high toughness and high strength. It can toughen ceramics by composing with the engineering ceramics. And it is considered as an ideal reinforcement phase in ceramic materials. In this paper, the toughening mechanism of carbon nanotubes (including grain refinement, toughness of short fiber and toughening mechanism of MWCNT’s collapse), and simulation results of the micro mechanical behavior of carbon nanotube and ceramic matrix interface by using the Shear-Lag-Model-Based Stress Analysis were discussed based on the carbon nanotube - ceramic composite experimental and researches. And then the comprehensive analysis of strengthening and toughening mechanism of carbon nanotubes in ceramic matrix is given, the current research problems are summarized and future research directions are considered.
