Monitoring of delamination during drilling of gfrp composites through acoustic emission and ultrasonic technique

Abstract

Composite materials have found variety of applications in newlinevarious fields of technology due to their mechanical properties and their newlinefavourable strength to weight ratio in particular Among the various newlineComposite materials Glass Fibre Reinforced Plastic GFRP Composites are newlinebecoming more important in aerospace naval and automotive industries newlineowing to their properties such as high strength to weight ratio and high newlinespecific stiffness as well as superior corrosion resistance light weight newlineconstruction low thermal conductivity high fatigue strength and resistance to newlinechemical and microbiological attacks newlineGFRP composites have the advantage of achieving the near net newlineshape depending upon the structural design requirement newline newline
