摘要:

碳納米管作為一維納米材料，具有重量輕及高強(qiáng)度、高韌性等優(yōu)異力學(xué)性能，與工程結(jié)構(gòu)陶瓷材料復(fù)合能夠強(qiáng)韌化陶瓷材料的力學(xué)性能，被認(rèn)為是現(xiàn)代結(jié)構(gòu)陶瓷復(fù)合材料理想增強(qiáng)體。本文綜合了近年來(lái)碳納米管增強(qiáng)陶瓷基復(fù)合材料在理論及實(shí)驗(yàn)方面的研究結(jié)果的基礎(chǔ)上。側(cè)重介紹了碳納米管增強(qiáng)陶瓷基復(fù)合材料的強(qiáng)韌化機(jī)理研究，如細(xì)化晶粒增韌、短纖維增韌和碳納米管獨(dú)特的坍塌增韌、多壁碳納米管抽出增韌機(jī)制，以及采用剪切滯后理論模型對(duì)碳納米管與陶瓷基體的微觀界面結(jié)合的力學(xué)性能的模擬研究結(jié)果。并對(duì)國(guó)內(nèi)外在碳納米管在陶瓷基體中的強(qiáng)韌化機(jī)理的實(shí)驗(yàn)及模擬研究結(jié)果進(jìn)行了綜合分析，總結(jié)了當(dāng)前碳納米增強(qiáng)陶瓷復(fù)合材料研究的困境、存在的問(wèn)題，并指出今后理論及實(shí)驗(yàn)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. Key words: Composite Material, Carbon Nanotubes, Ceramic Materials, Reinforced mechanism
