Investigation of Mechanical Properties of Layered Composites Formed from Glass, Carbon and Aramid Fibers and Aluminum Plates

Abstract

Technological developments and differences in application areas increase the importance of laminated composites. Laminated composites with complex properties exhibit features such as high strength, high corrosion and thermal resistance, low specific gravity, resistance to environmental conditions. These properties generally reflect components that make up laminated composite. In this study, effects of reinforcements on mechanical properties of laminated composites were investigated. In production of laminated composites, aluminum 5754 is used for metal layers, and aramid, glass and carbon fibers are used for fiber reinforcements. Epoxy was also preferred as resin. First of all, the resin was applied on the cleaned aluminum plate and the aramid fiber was added on it. By continuing the processes in this way, Arall laminated composite consisting of five layers was obtained. Similar processes were applied to carbon fiber and glass fiber materials, and Carall and Glare laminated composites were produced, respectively. In addition, by subjecting the fiber layers to a combination among themselves, Ar-Carall, Ar-Glare and Car-Glare laminated composites were produced. The produced laminated composites were subjected to tensile and bending tests and their strengths were compared. As a result of the experiments, the highest tensile and bending strength was obtained from the Carall laminated composite. The strength of the Ar-Carall and the Car-Glare laminated hybrid composites containing carbon fiber were better than the Arall and the Glare laminated composites.
