| Popis: | In this study, the effects of the addition of several solid lubricants on the hardness, bending stength, impact strength and tribological properties of COPNA SK resin were evaluated. The solid lubricants were polytetrafluoroethylene (PTFE), molybdenum disulfide (MoS2) and graphite (GP).The results are summarized as follows;1) The bending strengths for PTFE (20%), MoS2 (20, 30%) and GP-filled SK composites fall between 53-82MPa, which is 1.8-2.9 times as much as that of neat SK resin.The impact strengths for PTFE, MoS2 and GP filled SK composites fall between 0.12-0.49J/cm2, which is 2-8 times as much as that of SK itself.2) The limiting pv values for PTFE or GP filled SK composites are 2.8-4.8MPa·m/s, which is 1.4-2.2 times as much as that of SK resin itself.3) The wear rates of PTFE, MoS2 or GP filled SK composites are 0.2-3.4×10-4mm3/N·m. GP is the most effective filler to reduce the wear rate among these three solid lubricants.4) The frictional coefficients of these SK composites fall between 0.135-0.237. which is 0.35-0.8 times as much as that of SK resin itself. |
