Abstract: Composite materials are playing a greater role in engineering application due to their optimized structure and mechanical characteristics. Study here aims at composite design which enables the fabricated composite to have excellent mechanical behavior even in extremely corrosive environment, for example, environment with extremely high ozone gas concentration. To take advantage of the great anticorrosion property of pure aluminum (Al), PET thin film coated with pure aluminum (Al) on its surface has been introduced as the top layer of the fabricated composite with polyester textile as the middle layer. To bond these layers together, the composites with this sandwiched structure are manufactured at different temperature. Main purpose of the study is to evaluate the influence of processing temperatures on the mechanical properties of the manufactured composites, and on their failure behavior. In this way, optimized processing temperature may be found.
