Lightweight material structure is a crucial subject in product design. The lightweight material has high strength to weight proportion which turns into an immense fascination and a territory of investigation for the researchers as its application is wide and expanding consistently. Lightweight composite material design is accomplished by choice of the cellular structure and its optimization. Cellular structure is utilized as it has wide multifunctional properties with lightweight characteristics. Unless it has been topologically optimized, each part in a assembly most likely weighs more than it needs to. Additional weight implies abundance materials are being utilized, loads on moving parts are higher than would normally be appropriate, energy effectiveness is being reduced and increase in costs. Presently, with Topology Optimization innovation, products can be design durable, lightweight for any kind of applications. In this thesis, the design and forecast of cellular structure's performance are presented for developing lightweight cellular composites strengthened by carbon fibers. A 3D cuttlefish bone structure inspired by bio material is presented. With help of topology optimization and finite element analysis, analysis was directed on different volume percentage to characterize the cellular structure for its strength and stiffness. In addition, non-linear analysis was conducted to examine the behavior of the cellular structure with an-isotropic properties.
