Computational modeling of different Composite materialsmaterialsNatural fibers, including natural fiberNatural fibers-reinforced compositesComposites, has developed in parallel with experimental research in this field. As the mechanical and physical properties of these materials become better understood, computer simulations have been developed that predict their behavior under different conditions and help engineers design more efficient and resilient compositesComposites. Furthermore, it is well known that fiber-reinforced compositesComposites are widely used in impact load dissipation. This, coupled with topology optimization methods, can drive new structural designs that improve the performance of energy dissipation systems. In this work, natural hemp fibers were used to manufacture a fiber-reinforced composite materialComposite materials as the first layer, and an ABS polymerPolymer core was used as a flexible energy dissipation material. Natural fiberNatural fibers-reinforced compositesComposites, combined with topology optimization of the ABS polymerPolymer structure, generated an efficient impact energy dissipation system, which was subsequently modeled using the finite element method (FEM). To validate the results, the computational models were compared with the experimental ones, using the mechanical propertiesMechanical properties of the hemp compositeComposites and the ABS.
