Abstract

The impact damage and fatigue life is inter-linked in this work. The laminates were prepared by hand layup process having two different thicknesses; 2 and 4 mm. The specimens were subject to low-velocity impact at different energy levels (7.85, 15.7 and 23.54 Joules). The 2 mm thick laminates experienced higher deflection and the absorbed energy was low, when compared to 4 mm thick laminates. The fatigue test was conducted for both impacted and non-impacted laminates, by keeping the stress ratio, R value at 0.1 and frequency at 3 Hz. The results indicate that the impact velocity is very much influential on the fatigue life of composite laminate.  Further the results indicate that the fatigue life of the 2 mm thick impacted laminates was drastically reduced. A comparative study is also attempted to understand the behaviour of impacted laminates subjected to fatigue loading.
