摘要：
The aim of this study is to investigate the influence of hybridization on buckling behavior of composite plates consists of symmetrical and unsymmetrical ply orientations, various cutout shapes, and length/thickness ratio. Carbon, S-glass and Aramid fibers are used as reinforcement with epoxy resin. Experiments are performed to see the effects of various combinations of fibers on bucking loads with [(0/90)(3)](s), [(30/-60)(3)](s), [(45/-45)(3)](s) symmetrical and [0/90](6) unsymmetrical ply orientations. Numerical studies are also performed to see the effects of length/thickness ratio and various cutout shapes on the buckling loads. It is concluded that stiffness and shear properties are affecting buckling characteristics of the composite plates. Also, fibers having higher stiffness and higher shear properties in the upper layers increase the buckling strength. (C) 2014 Elsevier Ltd. All rights reserved.
