Abstract    Range of structural applicationof compositesin aircrafts, space-crafts, automobiles etc. has widely spread in the last few years. Enhancements in the materials are based on the requirements of the various aircraft components and parts which demand mainly high strength and reduced weight. Reduction in weight is mostly achieved by reduction in thickness and inclusion of notches or cut-outs. Other than weight reduction, cut-outs provide pathways to link different aircraft parts. According to the requirements different types of cut-outs such as square, rectangular, circular are used in various aircraft and automotive components.Cut-outs are also the cause of failure in many components as the stress concentration increases near the cut-out region and cracking occurs. So, to make an efficient structure, it is necessary to understand the effect of a cut-out on the mechanical properties of the composite material and the structure. In this paper, an experimental investigation was conducted to study the effect of a cut-out on the tensile strength of the Fiber Glass/ Epoxy composite plate. Geometry of the cut-out is one of the important factors which can critically alter the mechanical properties. So, cut-outs with various geometrical shapes such as square and circlewere introduced in the Fiber Glass/ Epoxy composite plate and tensile tests were performed under ambient conditions. It was determined from the tests that specimens with circularcut-out have higher tensile strength as compared to specimens with square cut-out.
