Abstract

<jats:title>Abstract</jats:title><jats:p>This paper presents comprehensive study on the tribological properties of PTFE (Polytetrafluoroethylene) hybrid composites using statistical tools. It identifies influential factors in the field of tribology, facilitating the development of improved materials and applications. PTFE hybrid composites are prepared by adding Graphite and MoS2 by compression molding followed by sintering. Orthogonal Taguchi layout(L18) is designed to conduct the Tribo-logical tests using Pin on Disc tribometer. The optimal parameters for wear and friction are observed at 25 wt.% of filler content, at a rotational speed of 1.20 m/s with a normal load of 30N. Furthermore, the significance of the factors is evaluated using ANOVA (Analysis of variance). The results indicated that the speed and filler composition are significant factors influencing the tribological behavior of hybrid PTFE composites. The contributions of speed, composition being 76.9% and 19.3%. The significant factors for co-efficient of friction are speed and filler composition of 50.56% and 9.93% respectively.</jats:p>
