This paper studies impact energy absorption characteristics of FRTP deep drawn structures having three representative shapes, i.e., hemi-shere, truncated cone and cylinder. Two kinds of woven fibers, i.e, glass fiber and jute fiber, are used as reinforcement. Three distinct P-U characteristics are obtained corresponding to the structural shapes, for both the cases. Deformation and fracture modes under impact compression are compared in terms of load-displacement (P-U) curve, total absorbed energy and its efficiency, and their interrelationships are extensively discussed.
