Flat Stiffened CFRP Panel Design and Analysis

Abstract The aim of this paper is to analyze the behavior of stiffened Carbon Fiber attached to a flat plate stiffener. The structural behavior of a composite plate with a flat plate stiffener has been studied in this research work. The aim is to investigate the effects of the stiffener on the stiffness and strength of the plate. The composite plates were made of layers of carbon fiber and the flat plate stiffener and it was made of aluminum alloy. The FEA results showed that the stiffener had a significant effect on the stiffness and strength of the composite plate. The addition of the stiffener increased the stiffness and reduced the deflection of the plate. The stiffener also increased the maximum stress and strain values in the plate, indicating an increase in the plate's strength.
