Study on the Tribological Properties of PTFE-Based Composites Materials Sliding Pair under Extreme Environment

In order to get PTFE(polyfluortetraethylene) composites of good friction and wear properties used in vacuum and low temperature conditions, do the tribological experiments of GF (glass fibre)/PTFE composites under vacuum and low-temperature environment. The results show that: with the increase of the GF size, the friction coefficient increases, with the increase of GF content, the friction coefficient increases.
