Friction Coefficient of Polymer and Composite Materials Sliding against Stainless Steel


Article Preview

An endeavor has been made to study and compare the friction coefficient of different polymer and composite materials. Experiments were carried out when stainless steel 304 (SS 304) pin slides on different types of composite and polymer materials such as cloth reinforced ebonite (commercially known as gear fiber), glass fiber reinforced plastic (glass fiber), nylon and polytetrafluoroethylene (PTFE). Experiments were conducted at normal load 5, 7.5, 10 N, sliding velocity 0.5, 0.75, 1 m/s and relative humidity 70%. Variations of friction coefficient with the duration of rubbing at different normal loads and sliding velocities were investigated. Results show that friction coefficient varies with duration of rubbing, normal load and sliding velocity. In general, friction coefficient increases with the increase in normal load and sliding velocity for all the tested materials except nylon. At identical operating conditions, the magnitudes of friction coefficient are different for different polymer and composite materials.
