Mechanical And Electro-Chemical Investigation Of Carbon Farbric/Epoxy And Aluminum Foam Sandwich Composite Beams, Narin Sara Fatima

Wayne State University Theses

In this study the mechanical and electrochemical response of a sandwich composite comprising of carbon fiber fabric skin and aluminum foam core was evaluated. The three point flexural test was chosen to investigate the mechanical behavior in terms of finding the deformation and failure behavior. The flexural test exhibited an excellent bond between the skin and the core. The specimens mainly failed in three different modes - indentation, core shear and face yielding and showed three distinct regions: a linear rise in load with displacement region, a rapid load drop region and a plateau region followed by a densification region. …
