Glass fabric reinforced thin sandwich panel and carbon fabric reinforced thin sandwich panel of thickness close to 2.5 mm were studied to explore an alternative skin material for the outer body of various machines and appliances. The polyester foam Coremat XM of 2 mm thickness was used as core material in the thin sandwich panels. The panels were fabricated by vacuum bagging process and characterized through two plate tests: (i) low-velocity normal impact loading under a drop weight impact test set up and (ii) transverse static loading of a plate. The damage area, indentation depth and permanent depression over damage area, energy absorption capability, load-deflection relation and failure modes were observed under the test. The impact drop test was simulated by LS-DYNA. The properties of glass fabric reinforced thin sandwich panel and carbon fabric reinforced thin sandwich panel were compared with those of 0.8-mm-thick MS sheet, a widely used skin material for the outer body of various machines and appliances.
