Increase in demand of advanced materials to satisfy the requirements of aerospace and automotive industry viz. high modulus to density ratio, leads to the research in composite materials where an attempt is made to study the properties of composite materials by composing the different materials together to obtain the desired properties by reducing the weight as much as possible. Here an attempt is made to study the behavior and tensile properties of Hybrid polymer composite material by composing E-glass fibres, carbon fibres and graphite with epoxy resin 5052. By the variation of thickness. Tensile strength of hybrid composite is observed for each thickness and is optimized and compared with the properties of standalone glass fibre reinforced composites for the same variation of thickness. The comparison represents the enhancement of tensile strength and cost effectiveness by the introduction of multiple materials (Hybrid composites)
