Dramatic improvement in Mechanical properties and SEM image analysis of Al-CNT composite

In the last decade, as demand for high quality materials are increased, the development of lightweight aluminum (Al) also increased especially in aerospace and automotive industries. It has been well known that Al based metal matrix composites (MMCs) offers a very low thermal expansion coefficient, high specific strengths, wear and heat resistance as compared to conventional Al alloys. In order to combine all these properties, MMCs have become a very attractive method for various industrial applications. The interest in Carbon Nano Tube (CNT) as reinforcements for aluminum (Al) has been growing considerably. Efforts have been largely focused on investigating their contribution to the enhancement of the mechanical performance of the composites. The uniform dispersion of Carbon Nano Tube in the Al matrix has been identified as being critical to the pursuit of enhanced properties. In this present research paper emphasis, the effect of Carbon Nano Tube content on the Mechanical properties of the composites like Tensile strength, Percentage of Elongation was investigated. The improvement of mechanical properties for composites of Al/CNT has been compared with pure aluminum.
