Abstract: Elastic properties are the basic quantities that are required during design and optimization of a laminated structure. Though the literature on elastic properties of conventional single fibre composite is well published, the same is scanty in the case of natural and hybrid composites. This work is focused on evaluation of in-plane elastic properties of untreated woven jute and jute-glass fabric hybrid polyester composites, under tension. The specimens have been fabricated by hand-lay-up technique with different relative weight fraction of jute and glass fibre. Theoretically, the laminate elastic properties are predicted by using the classical lamination theory (CLT) and rule of hybrid mixture model, using the resin and fibre properties together with the volume fraction (micromechanics). Experimentally, the elastic properties have been evaluated by tension test in warp and weft direction and in-plane shear test as per ASTM standards. The results indicated that the Young’s modulus in both warp and weft direction improve by the inclusion of glass fibre, where as Poisson’s ratio is decreased. Prediction by CLT and model showed close agreement with experimental values with a maximum deviation of about 20%. The possible causes for this deviation are discussed.
