Abstract: Sandwich panels made of thin polymer composite materials have been developed and characterized as an alternative material to the mild steel sheet sheets conventionally used as face sheet materials [outer cover] for refrigerator, washing machine, and in automotive appliances like automobile, boat etc. In this paper sandwich panel made of Glass Chopped Strand Mat (GCSM) face sheets with polyester foam Coremat XM, polyester foam Coremat Xi and jute are fabricated. Flexural behavior of sandwich panel is studied. Theoretical results of sandwich panel is compared with 0.8 mm M.S. specimen conventionally used for manufacturing the body of automobile, cover of many machines and appliances. The load versus deflection relation of sandwich panel is almost linear. The strength and deflection are calculated theoretically by the equations derived from theory of bending. From the results It is found that sandwich composite have quite superior properties, which can be used for various engineering applications.
