Experimental Study of Abrasive Wear Behavior of CFRPs Using Rotary Platform Abraser with Varying Abrasive Grain Size and Fiber Contact Angle
The experimental investigation was conducted to study the wear morphology of Graphite/Epoxy composite material on Taber rotary platform abrader at a constant load of 1250 grams for duration of 10000 cycles. Wear behavior was presented in terms of material removal rate, surface texture and roughness characteristics for varying abrasive size. It was found that the contact angle between the fiber and the interacting abrasives affected the wear mechanism and which in turn affected the roughness. Higher wear preferentially occurred in a specific range of fiber-abrasive interacting/contact angles. The wear rate was found to decrease with increasing surface roughness but increase with increasing abrasive size. The surface and sub-surface delamination was studied through scanning electron microscopy and surface statistics associated with wear roughness will also be presented.
