Evaluation of mechanical properties on Tio2/GF reinforced nylon66 composites

Abstract

Abstract The research on Mechanical and Tribological properties using nylon66 composites with Tio2 at various volume fractions are taken into consideration. The tensile strength, compressive strength, Modulus and Flexural strength tests were performed on specimen prepared by twin screw extruder. It was observed that there is increase in heat deflection value, wear arte along with increase in the coefficient of friction. For effectiveness in the Tribological properties of nylon66 + Tio2 it was combined with glass fiber as filler material. Some of the tests were conducted on the pin-on-disc apparatus and analysis through SEM to study about the wear behaviour of the material. This resulted in the improvement of the Tribological, thermal and mechanical properties of the composites with reduction in wear rate and coefficient of friction up to 4 wt% of Tio2 filled with glass fiber. It was also analysed that at 2 wt% of Tio2 filled with 2 wt% glass fiber there is effective enhancement in Tribological properties along with decrease in coefficient of friction and wear rate.
