Analysis and evaluation of drilling induced damage in fiber reinforced polymer composites: A review

Abstract

Fiber reinforced composite materials are very competent materials to be used in a wide spectrum of engineering applications ranging from house hold appliances to aerospace components. Drilling operation is heavily performed machining operation while fabricating a fiber reinforced polymer composite based product. Delamination at the entry and exit side of the laminate is dominant damage while making holes in composites which leaves the component unusable. The analysis and evaluation of delamination should follow some standards in order to compare the damage effectively. The present paper reviews various methods adopted by the researchers to analyze and evaluate the drilling induced damage commonly known as delamination in fiber reinforced polymer composites.
