Dry sliding wear behavior of GFRP with liquid silicon rubber and reinforced with fine silica powder by Taguchi approach

This paper deals with the study on wear behavior of Glass Fiber Reinforced Polymer (GFRP) with liquid silicon rubber reinforced with fine silica powder by pin-on-disc test rig. Hybrid GFRP composite laminates are prepared by compression molding technique at constant process parameters like Pressure: 100kgf, Temperature: 50 °C and Time: 40 min. The tests are performed as per the ASTM standards G 99-95. The variables: load, speed and time are optimized by making use of Taguchi technique. The results shows that, wear rate is more in material having weight fraction 50:50 from fiber to matrix than in material having 60:40 weigh fraction. The wear resistant is more in material -1(60% GFRP+32% LY556 Resin+4%SR+4% Silica Powder) having 60:40 weight to matrix ratio. The results were validated by confirmation test by experimental and comparing with predicted results from the regression model.
