文摘

Tribological behavior of PTFE composites is well known to be affected by factors depending mainly by matrix and filler properties. However, the mechanism taking place has not still been fully explained. In this work, the attention was focused on the variation of crystallinity due to the presence of fillers and it was connected with the transition phases to which the PTFE is subjected. In particular, a simplified frictional heating calculation method was used for estimating the maximum contact temperature and results were connected with differential scanning calorimetry analyses (DSCs).
