Change of mecahnical properties of polytetrafluoroethylene(PTFE) were examined by means of 
irradiation of the moulding powder prior to compression moulding. Share strength and elongation of PTFE incresed 4 times with incresing of the radiation dose, whereas tensile strength maintained inrinsic value. Gas transmission rate of nitrogen and oxygen were also considerably controlled to lower value. These results suggest that the irradiation effect on PTFE mouling powder are useful for industrial applications.

Times Cited Count：12 Percentile：63.98(Chemistry, Physical)Plain-woven carbon fber-filled polytetrafluoroethylene (PTFE)composites were fabricated by radiation-crosslinking under selective conditions.High mechanical and frictional properties are found in the composite materials compared with crosslinked PTFE without fiber.The composite materials with optional shapes,which are laminated after electron beam (EB) crosslinking treatment of each mono-layer could also be fabricated.
