Abstract: Fiber reinforced polymer (FRP) composites are an important class of tribological materials. Theyrnpossess unique self-lubrication capabilities and low noise which make them suitable for applicationsrnlike seals, bearings, gears. The FRP composite bearings are ideal for high load, low speed applicationsrnor where normal lubrication is difficult or costly. For the purpose of fully utilizing the beneficialrncontact characteristics of FRP composites, it is necessary to obtain an in-depth knowledge of theirrncontact behaviour.rnThis work attempts to apply Hwu and Fan’s analytical solution to FRP composite bearings in order tornobtain a better understanding of their compliance behaviour. The frictional sliding contact between arnFRP composite and a rigid parabolic cylinder was analyzed. The influence of sliding direction, fiberrnand matrix material combinations, volume fraction of the fiber, friction coefficient and fiber plyrnorientation on the contact pressure distribution and the contact area for unidirectional FRP compositernbearings were evaluated. The finite element model was developed using ANSYS 10.0 and the resultsrnobtained from FEM were compared with the analytical results. The influence of sliding direction onrnthe contact pressure distribution for cross ply FRP composite bearings was studied and compared withrnunidirectional FRP composite bearings. The contact parameters for unidirectional FRP compositernbearings were optimized using genetic algorithm.
