Honeycomb mainly known for is high strength to weight ratio. Its sandwich structure is made of three layers, First and third layer is skin, made of metal, alloys of metal or may be from composite material like fiberglass, high pressure laminate. This light weight structure is mainly part of aerospace industries. Its high impact absorbing capacity attracted many researchers to investigate the effect of core between two skins. This paper aims to analyze impact absorbing capacity of specimen. An impact absorbing capacity of the specimen is determined up to full penetration by experimental drop weight test. The Core hexagonal cell configuration with variation in their cell size has been considered. The six specimens are tested to determine the relation between force and deformation by considering peak and puncture factors for force, deformation. The variations in cell size reveals that 40% energy absorbing capacity increase in results.
