The morphological changes of the PTFE composite during the sliding were related to the variation of the tribological properties to analyze the underlying wear mechanisms. Results show that the coefficient of friction and wear rate change with the increase of temperature. During the sliding, three regions can be identified regardless of the temperature. The high temperature is beneficial to the formation of tribo-film. The sequence of wear evolution is PTFE removal, load transfer to glass fiber, and minor formation of tribo-film for the low temperature condition. For high temperatures, the wear behaviors are more complicated. The different phenomena include the third body abrasion, flake delamination of PTFE matrix, scratching and reformation of transfer film on the counterface, and the filling of the large scale PTFE groove. These behaviors may dominate the different stages in the stable region, but occur simultaneously and cause the dynamic steady wear. As a result, the wear rate at 200 \u00b0C is slightly fluctuant.<\/jats:p>","DOI":"10.3390\/ma12071082","type":"journal-article","created":{"date-parts":[[2019,4,3]],"date-time":"2019-04-03T03:39:28Z","timestamp":1554262768000},"page":"1082","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Wear Evolution of the Glass Fiber-Reinforced PTFE under Dry Sliding and Elevated Temperature"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7156-4856","authenticated-orcid":false,"given":"Ruoxuan","family":"Huang","sequence":"first","affiliation":[{"name":"Department of materials science and engineering, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Siqi","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of materials science and engineering, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meidi","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of materials science and engineering, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Yang","sequence":"additional","affiliation":[{"name":"Key Lab of Ship-Maintenance &amp; Manufacture, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dehong","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Lab of Ship-Maintenance &amp; Manufacture, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Shanghai Micropowers Ltd., Shanghai 201203, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiujun","family":"Xu","sequence":"additional","affiliation":[{"name":"Key Lab of Ship-Maintenance &amp; Manufacture, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"16518","DOI":"10.1021\/acs.jpcc.5b00947","article-title":"Interrelated Effects of Temperature and Environment on Wear and Tribochemistry of an Ultralow Wear PTFE Composite","volume":"119","author":"Khare","year":"2015","journal-title":"J.
