| Abstract | This paper presents the low-velocity impact response of woven E-glass fiber/galvanized iron metal laminate. The fibre metal laminates were prepared with different stacking sequences of 2/1 and 4/5 using hot compression technique and subjected to drop-weight impact according to ASTM D7136 for three different impact loads, i.e., 10 J, 20J, and 30J. The impact response of the fiber metal laminates (FMLs) was compared to those of pure woven glass fiber reinforced polymer (WGFRP) laminate and plain Galvanized Iron (GI) sheet metal in terms of peak load, maximum deflection, absorbed energy, specific absorbed energy, load-deflection behaviour, and damage area. The increased impact energy is attributed to the higher peak load, maximum peak load, absorbed energy, and severe damage area. It was found that the FML with stacking sequence 4/5 (FML 4/5) exhibited the highest peak load when subjected to 20J and 30J impact energy loading and also exhibited the maximum deflection when compared to the other laminates. This indicates that FML 4/5 has high ductility and thus, absorbs a higher impact load. Based on the damage areas, it was observed that the FMLs were dominantly failed by composite/metal interface delamination. |
