Abstract: To realize the recycling and reutilization of polytetrafluoroethylene （PTFE） materials， the suppressed and unsintered PTFE arc extinguishing nozzle blank was preprocessed， and then its scrap was collected to obtain recycled PTFE （R-PTFE） powders. The R-PTFE/MoS2/glass fiber （GF） composite were obtained by incorporating 5 wt% MoS2 and 15 wt% glass fiber into the R-PTFE） powders. Based on the particle size and scanning electron microscopic analysis results， the R-PTFE powders exhibited a fine particle size after crushing three times. The mechanical test results indicated that the R-PTFE/MoS2/GF composite obtained optimal mechanical performance when incorporating 300-mesh glass fiber powders into the R-PTFE powders after crushing three times， and its tensile strength and elongation at break were 13.17 MPa and 352.58 %， respectively.

Key words: polytetrafluoroethylene, scrap material, recycle, glass fibre
