Study of Static and Dynamic Behavior of Aluminum Composite Beam
In this report the given information is related to the sandwich structured composite panel/beam/plate. The sandwich material panel is made up of three layers: low density core inserted between two relatively thin skin layers. A special class of composite materials is sandwich-structured composite which are fabricated by attaching the two thin but stiff skins to a lightweight but thick core.
Sandwich panel construction is one of the first cores or forms of composite structures to have attained wide acceptance and usage. Sandwich structures are broadly used in helicopters and airplanes including military aircraft and space vehicles. Sandwich panel is made of Aluminium (Al) material is used as skin material and Polyurethane (PU), Polyethylene (PE) materials were used as a core material. Skin and core material is attached together with the help of resin, after preparation of sandwich plates it’s testing carried out on the universal testing machine (UTM) and natural frequency calculated on fast Furrier transform (FFT) and also damping characteristics calculated. At last comparison between the FFT finite element analysis (FEA) has been shown. At last result and conclusion are discussed.
