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.
