FABRICATION OF COMPOSITE STIFFENED PANEL

Abstract

A Composite materials are widely used in aerospace structures due to their high strength-to weight ratio and high stiffness-to-weight ratio as compared to conventional materials.Well-judged combination of materials along with the specific type of engineering structures, stiffened structures, provide tailored properties for aircraft structural components. In this work, the design and fabrication of composite stiffened panel is studied Being such a widely used structural component (composite stiffened panels) in aerospace industry, effective fabrication and assessment of integrated composite stiffened panel become a major interest in the research community. Being a thin-walled structure, the behavior of composite stiffened panel is governed its stability criteria. Therefore, the experimental study can be carried out to understand the stability behavior of laminated composite stiffened panels, in terms of buckling loads and failure loads. Key Words: A Composites, stiffened panels, stiffeners, aircraft structures, buckling/failure load
