Compressive Failure Behaviour of Kevlar Epoxy and Glass Epoxy Composite Laminates Due to the Effect of Cutout Shape and Size with Variation in Fiber Orientations

The increasing trendof constructing componentsmade of composite laminates is due tothe flexibility intailoring their properties and high strength-to-weight ratio. Nevertheless, most practical components involve cutout features for fastening these cutouts could significantly reduce the strength laminate. Due to its importance, many studies were conducted study effect circular however, there lack information regarding various shapes. Therefore, this aims investigate compressive failure behaviour Kevlar Epoxy Glass different shapes sizes with variation in fiber orientations. Finite element software, ANSYS used simulate deformation under load. Prior that, mesh convergence analysis numerical validation performed. Failure was (square cutout, diamond circular) size, based on Maximum Stress Theory. results show that existence have reduced up ten times laminated plates. This important when designing made compression.
