Tribological properties of polytetrafluoroethylene composites filled with rare earths modified glass fibers

Tribological behavior of poly (phenyl p-hydroxybenzoate)/polytetrafluoroethylene composites filled with hexagonal boron nitride under dry sliding condition

“…Yet, PTFE cannot be used as anti-wear material alone because of its poor mechanical properties, bad thermal conductivity and high wear rate. In order to improve its anti-wear properties, PTFE is usually reinforced by inorganic or organic fillers such as glass and carbon fiber [1][2][3], graphite [4,5], bronze powder [6] and a good number of inorganic fillers [7][8][9]. Usually, the combination between these inorganic fillers and PTFE matrix is often poor; this will decrease the strength and wear resistance of PTFE/inorganic filler composites to a large extent.…”
