Abstract
FRPCs are highly susceptible to impact damages such as drop tools, hail stones, shocks, vibrations, and overload. Hybridization of fibers is one of the effective method to improve the damage resistance characteristics. The incorporation of nanoparticles in matrix material enhance the toughness of polymer composites leads to improve the fatigue life the components. In this work, the effect of addition of nanoparticles and hybridization of fibers on fatigue life of the FRPCs was investigated without compromising the stiffness and cost. Three sets of CGFRP laminates namely (45°G/0°C/45°G)S and (45°C/0°G/45°G)S, (45°C/0°G/45°G)S lay-up sequenced laminates were prepared using hand layup process. The low velocity impact (LVI) test was conducted on the CGFRP specimens in accordance with ASTM D5628F standard. After that both the impacted and non-impacted composite laminates were tested for their fatigue life with the constant stress ratio R. The stress vs number of cycles curve were plotted using the fatigue testing set-up.
