Abstract    Polymer-based composites are extensively used in different industrial applications such as bearings, cams, gears, clutches, etc. due to their enhanced mechanical properties and light weight. These materials are subjected to friction and wear conditions. Hence, there is a need to study the dry wear properties of these materials. This investigation has analyzed the dry sliding wear properties of glass/carbon reinforced hybrid composites. The wear properties of these composites were investigated with different operating conditions (composite hardness, sliding distance and applied load). Design of Experiment (DOE) was used to construct different models based on Box-Behnken design. Response Surface Methodology (RSM) was employed to optimize the various experimental parameters to minimize the wear rate of hybrid composite. A second order mathematical model has been developed and the predicted optimum input parameters are [GCGGC]S composite, 1100m sliding distance and 33.15N applied load. In addition to that the predicted results found a close agreement with the experimental one.
