Investigation into the Effect of Aluminium Powder on Mechanical, Tribological and Electrical Properties of Al-Abs Composites
Authors: ,
Abstract: Nowadays many advanced technological processes require materials with unusual combinations of properties that cannot be provided by the traditional polymers, ceramics, and metal alloys. Because of these the focus is shifted from the pure/traditional material to the composites/hybrid materials for manufacturing the product. In view of this objective of the present study was to investigate the effect of different composition of aluminium (Al) powder on the mechanical properties of the ABS-Al composites. Three different compositions of ABS-Al composite with different weight percentage of surfactant material were prepared using injection molding machine. Mechanical properties such as tensile strength, flexural strength, impact strength and hardness test, tribological properties and electrical resistivity test were performed on these composites as per ASTM standard. Experimental results showed that the mechanical properties of composites are less in comparison to plain ABS. Hardness of Al-ABS composites is low in comparison to plain ABS material. This is due to the fact that the aluminium is soft material and undergoes more deformation resulting in low hardness value. Wear test results showed that the height loss and coefficient of friction of composites is more in comparison to plain ABS. Electrical resistivity of composites is less than the plain ABS and the resistivity decreases as the aluminium percentage increases in the composites. This is due to the fact that ABS is a bad conductor of electricity and aluminium is good conductor of electricity. Thus, this study reveals that based on applications a particular type of Al-ABS composite can be used.
