Abstract |
Glass fiber reinforced plastic GFRP composite materials are a feasible alternative to structural members that bear loads under different conditions. However, drilling of such composite materials generally tend damage the area around the drilled hole which thereby acts as a hindrance to their application. This hole in turn acts as a stress concentration layout for failure under dynamic loading. The present study is one such attempt to study the influence of drilling-parameters on the ultimate compressive strength of randomly oriented GFRP composite laminates of 70:30, 60:40 and 50:50 glass fibers and epoxy volume concentration. It was observed that material composition of 70:30 glass-epoxy yielded the maximum value for Ultimate compressive strength when compared to compositions of 60:40 and 50:50. It was also observed that value of compressive strength decreases with increase in speed. Mathematical models correlating ultimate compressive strength with the drilling parameters have been developed and are found to agree well with the experimental ones.
