Abstract :

Hybrid composites are a kind of composite produced with two or more different reinforce. One of the production technologies is using metal-fiber layers in a hybrid composite. In the present study, for the production of Hybrid composite, samples were prepared from glass fiber (S glass), aluminum alloy sheet (2024), and epoxy resin (F grade) using Resin Transfer Molding (RTM) process. Thus, three samples were considered, not strengthened matrix samples, samples with two layers of glass and samples with two layers of glass and two layers of aluminum. Then amounts of rigidity, strength and density of the samples were calculated considering fibers volume fraction. The results indicate that the presence of aluminum layer leads to an increase in toughness and plasticity of the composite, and thus causes more resistance to damage. Besides ultimate strength and strain, Natural frequency of the samples also increases by addition of the aluminum layer.
