DEVELOPMENT AND ANALYSIS OF HIGH SPEED DRILLING INDUCED DELAMINATION IN GLASS FIBER REINFORCED POLYMER

Composite materials are increasingly popular in various fields for its advantages
in physical and mechanical properties. However, the wider applications of composite
materials have often been hindered due to the difficulty and high cost associated with
shaping and machining them into damage free composite parts with requisite
tolerances and surface finish. The objectives of this research arc to develop and
analyze drilling induced delamination during high speed drilling of glass fiber
reinforced polymer (GFRP). The GFRP composite was designed and fabricated with
less that 5 % void content using vacuum resin infusion technique with fiber volume
fraction higher than 55 %, suitable for structural application.
