Biodegradable composites are highly encouraged to replace the traditional composites to promote the frangibility and environmental sustainability. In this paper, impact response of natural fiber reinforced composites is carried out by using drop mass set-up. Sisal and coir fibers are reinforced in epoxy matrix and the laminates are made by compression moulding process. Experiments are conducted to predict energy absorption and peak contact force during impact of 6 kg mass. Results are analyzed to find suitability of natural fiber reinforced composites in order to derive the suitable materials for frangibility application. © 2017 Trans Tech Publications, Switzerland.
