Devendra B. Sonawane | Prof. R. N. Garad | Pratik K. Satav

Abstract: Reducing weight while increasing or maintaining strength of products is getting to be highly important research issue in this modern world. The rectangular steel sandwich structure which is used in application of aircrafts, wind turbine blades, marine, space and also in other industrial sectors. Steel sandwich structure with top and bottom plates as well as core made up of steel called as steel sandwich structure. In this paper replacement of core of Rectangular steel sandwich structure with core which glass fiber reinforced polymer (E-glass/epoxy) and top and bottom plates made up of mild steel is used due to high strength to weight ratio and good corrosion resistance. In this paper analysis of rectangular steel structure and rectangular composite structure is done in Ansys work bench and Total deformation and equivalent stress is analyzed. The model of composite structure is generated in CATIA. Result shows that, the rectangular composite structure has stresses much lower than rectangular steel structure and weight of rectangular composite structure is reduced.
