Tribological study and parameters optimisation of CNT added glass fibre reinforced polymer composite sliding under inert environment

ABSTRACT

The primary goal of this research is to examine the effect of loads, sliding velocity, and sliding distance on CNT added glass fibre reinforced polymer composite sliding in the inert gas condition. The wear performance of the CNT added GFRP composite sliding towards the steel alloy wheel was analysed by important tribological parameters. The results clearly show the subjective influences of the wear parameters and their impact on the rate of wear and the coefficient of friction (COF). The Response Surface Methodology (RSM) confirms the potential spectrum of responses. Also, it defines the optimum value of process factors like applied load, sliding distance, and sliding velocity, which results in a decreased response over the long life of the composite applied. The optimum solution for wear rate and COF, predicted using the design of experiment (DOE) technique in conjunction with the RSM methodology, allows users to choose the appropriate wear rate and COF combination. The asperities on the disc and the pin are well separated under inert gas conditions. Furthermore, because asperity contacts provide the least frictional heat, the development of wear debris is significantly delayed. As a result, the COF and wear rate are both at their lowest.
