Development in the industry always requires creation of novel materials that meet the requirement of the new designs and market. Fiber reinforced composites are recently proposed in many applications such as military, aerospace and marine structures, automotive and piping due to their strength to weight ratio, high stiffness, and decent fatigue tolerance. Despite these advantages, the low impact resistance renders its application in many critical designs and reduces its applicability in the current structures. Inspired by many biological structures in nature, bio-inspired composites have been proved to exhibit a significant improvement over conventional structures in energy absorption capacity [1]. This work will present the improvement of strength and ductility by using bio-inspired composite laminates [2]. The Impact and post-impact response of hybrid bio-inspired composite laminates will be discussed [3].
