| Abstract | ||||
| A pin on disk machine is designed and constructed to experimentally measure and investigate the friction coefficient and wear rate of two groups of compounds of (PET) – CNT, and PET – CNT and paraffin oil under variable applied loads. Polymeric Composites Reinforced by Nano Particles and Impregnated with Paraffin Oil have low friction coefficients and highly resistant to wear so it is widely used in aerospace, automobiles, packing materials and in bearing applications. The effect of both percentages of PET with CNT and PET, CNT and paraffin oil under variable loads on coefficient of friction and wear values are carefully recorded and studied. A historical review of the available published work has shown a need for this work. This research used test specimens were prepared by casting method. The Addition of carbon Nanotubes to the polyethylene terephthalate with specified contents of Group I showed decrease in friction coefficient and wear values with increasing CNT content and applied loads. The tested specimens of Group II were filled by 3, 5, 10 wt. % paraffin oil introduced with the composites of PET and CNT. Applied loads of 8, 13, 18, 23, 28, 33 N were used during the test. The coefficient of friction was calculated by dividing the frictional forces by the applied normal load. Specimens were weighed before and after the test and the difference between the two weights represented the wear loss. Results of conducted tests on the compound of PET and CNT and paraffin oil under the previous loads were plotted for friction coefficient as of CNT content showed decreasing trend of friction coefficient with increasing the content of paraffin oil. According to increase of the applied loads of wear rate decreased. Finally, this research proposes a good assessment of testing polymer matrix for various applications such as bearing materials and guide ways. | ||||
