Influence of Circular and Square Cut-Outs on Fiber Glass/Epoxy Composite Laminate Under Tensile Loading

Use of composites for a range of structural application in aircrafts, space-crafts, automobiles, etc., has widely spread in the last few years. other than weight reduction, cut-outs provide pathways to link different aircraft parts. 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 circle were 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 circular cut-out have higher tensile strength as compared to specimens with square cut-out.
