本文描述了通过新型絮凝技术和放电等离子烧结（SPS）方法制备的多壁碳纳米管（MWCNT）/氧化铝复合材料的机械性能。研究了烧结温度、酸处理温度和MWCNT体积分数等工艺参数对复合材料力学性能的影响。研究发现，本研究制备的高体积分数多壁碳纳米管复合材料中，多壁碳纳米管在氧化铝基体中分散良好。较低的烧结温度和较高的酸处理温度可以使MWCNT含量为5 vol.%，甚至10 vol.%时保持和提高弯曲强度和断裂韧性。
This paper describes the mechanical properties of multi-walled carbon nanotube (MWCNT)/alumina composites prepared by a novel flocculation technique and spark plasma sintering (SPS) method. The influences of processing parameters including sintering temperature, acid treatment temperature and MWCNT volume fraction on the composites’ mechanical properties were investigated. It is found that the well dispersed MWCNTs within the alumina matrix were obtained in the high volume fraction MWCNT composites prepared in this research. Lower sintering temperature and higher acid treatment temperature could lead to the maintenance and increase of bending strength and fracture toughness with the MWCNT fraction of 5 vol.%, even 10 vol.%.
