Abstract Here, the effect of stacking sequence on the mechanical and thermomechanical properties of composites using natural fiber (jute), synthetic fiber (glass) and unsaturated polyester resin, is presented. The fabricated composite laminates were neat jute/polyester, neat glass/polyester, and hybrid jute/glass/polyester. It was revealed that neat glass/polyester laminate showed better mechanical performance than the other laminates, and glass fiber hybridization significantly affects the properties of the hybrid laminates. Furthermore, three selected composites were studied using Dynamic Mechanical Analysis (DMA) and Scanning Electron Microscopy (SEM) imaging. Lastly, to improve the mechanical properties of the developed composites, 1 kGy dose of γ-irradiation was applied. As a result, the tensile strength, bending strength, tensile modulus, and bending modulus was increased 10.7, 26.7, 21.5, 36.5% for neat jute/polyester composites; 6.2, 10.9, 50.3, 18.0% for neat glass/polyester composites; and 8.9, 11.9, 21.7, 19.9% for hybrid composites, respectively.
