This study introduced a novel fabrication of aluminum—carbon nanotube (CNT) composites by employing bulk acoustic waves and accumulative roll bonding (ARB). In this method, CNT particles were aligned using ultrasonic standing wave in an aqueous media, and the arrayed particles were precipitated on the aluminum plate substrate. Then, the plates rolled on each other through the ARB process with four passes. Optical and scanning electron micrographs demonstrated the effective aligning of CNTs on the aluminum substrate with a negligible deviation of arrayed CNTs through the ARB process. The X-ray diffraction pattern of the developed composites showed no peaks for carbon and aluminum carbide. In addition, tensile tests showed that the longitudinal strength of the specimens processed with aligned CNTs was significantly greater than that of the specimens with common randomly dispersed particles. The proposed technique is beneficial for the fabrication of Al—CNT composites with directional mechanical strength.

这项研究介绍了一种通过利用体声波和累积滚动键合（ARB）来制造铝碳纳米管（CNT）复合材料的新型方法。在该方法中，使用超声波驻波在水性介质中使CNT颗粒取向，并且将排列的颗粒沉淀在铝板基板上。然后，板通过ARB工艺以四道次彼此滚动。光学和扫描电子显微照片表明，通过ARB工艺，碳纳米管在铝基板上的排列有效，而排列的碳纳米管的偏差可忽略不计。所开发的复合材料的X射线衍射图没有显示出碳和碳化铝的峰。此外，拉伸试验表明，用对齐的CNT处理的样品的纵向强度显着大于具有普通随机分散颗粒的样品的纵向强度。所提出的技术对于具有定向机械强度的Al-CNT复合材料的制造是有益的。
