Abstract
Hybridization is a technique to enhance the mechanical properties of composites. This paper aims to investigate the effect of hybridization on the buckling behavior of fabric-reinforced composites experimentally, numerically, and theoretically. For this purpose, uniform and hybrid laminates were produced using glass and carbon woven fabrics and epoxy resin. The buckling test were carried out on the prepared samples. The results showed that the hybridization technique enhance the critical buckling loads of laminates. Also, the location of laminas in hybrid laminates significantly affects the buckling behavior of laminates so that the maximum critical buckling load (538.9 kN) belongs to the laminate where the carbon-fabric-reinforced laminas are in outer layers, and the minimum (201.3 kN) belongs to the sample whose outer layers are glass-fabric-reinforced laminas. In addition, a very good correlation was observed between theoretical and numerical results of buckling simulation, which predicted the critical buckling load in FEM based software (ABAQUS).
