Abstract :This study explores the effects of nanoclay addition on mechanical response of Glass/Carbon/Glass fiber insert ignore into journalissuearticles values(G/C/G); reinforced epoxy matrix composite laminates under tensile and flexural loadings. Organomodified nanoclay containing Glass/Carbon/Glass hybrid composite laminate was evaluated for dynamic mechanical properties as well as mechanical strength, stiffness and ductility. Two different types of fiber reinforced hybrid composites were manufactured. The amount of nanoclay additions were 0.75 wt % and 1.25 wt % with respect to epoxy resin and hardener. A nanoclay containing epoxy – Glass/Carbon/Glass hybrid composite laminate were manufactured by using a hydraulic hot press. Then, tensile, flexural tests and dynamic mechanic analysis insert ignore into journalissuearticles values(DMA); was implemented to ASTM standard specimens which were cut from the plates by using abrasive water jet cutter. Uniaxial tensile and three-point bending tests have been carried out to obtain some mechanical characteristics such Young’s modulus, tensile strength, break strain, flexural strength and modulus of the hybrid composites. DMA measurements also performed to compare nanoclay effect. The results of this study demonstrated that the mechanical behavior was positively affected by nanoclay addition into epoxy resin. The tensile strength and flexural strength significantly increased compared to the non-nanoclay hybrid composite insert ignore into journalissuearticles values(pure);. However glass transition temperature insert ignore into journalissuearticles values(T g ); of hybrid composites decreased with increasing amount of nanoclay.
