PTFE's wear resistance is improved by adding fillers

Abstract

The study of dry sliding composites made of polytetrafluroethylene, more commonly known as PTFE, is the focus of this paper. In fact, the conventional bearing materials have a high coefficient of friction and a high wear rate. PTFE is a self-lubricating material with low wear rates and excellent chemical and dielectric properties. The PTFE material has a high coefficient of friction—certainly lower than that of conventional materials—so the addition of fillers can mitigate this issue. There are numerous radially available PTFE composites on the market; however, the effects of varying load, sliding distance, sliding velocity, and filler content in PTFE are experimentally examined for 20% glass fiber and 25% carbon in this study. It has been discovered that the original properties of PTFE are getting better as fillers are added. To collect controlled data, a plan of experiment based on the Taguchi technique was carried out. The experimental results have been tallied, and they show that virgin PTFE's wear performance has improved as a result of the addition of fillers. By varying various parameters like load, velocity, and sliding distance, it was discovered that PTFE containing 20% glass fiber had superior wear performance.
