Examines friction and wear improvements in epoxy with chopped carbon fibers and oils, suggesting better performance with specific additives.
This article discusses the influence of filling epoxy by chopped carbon fiber and various kinds of oil (olive, corn, sunflower, glycerin and paraffin) on the friction and wear. Different concentrations of each oil (2, 5, 10 wt. %) were added to epoxy resin in addition to 2 wt. % chopped carbon fiber. Experiments were conducted using pin on disc test rig. The tests were carried out at constant speed (0.93 m/sec), constant load (6.5 N) and constant running time (300 sec) at room temperature. The worn surfaces of tested specimens were observed using scanning electron microscope. The results revealed that reinforcing epoxy by chopped carbon fiber has significantly affected the friction behavior and wear resistance. Moreover, addition of green oils (olive, corn, sunflower and glycerin) and mineral oils (paraffin) to epoxy/carbon fiber composites enhanced the friction and wear properties.
