The vehicle’s weight has a considerable impact on the overall economy of electric cars (EVs). When the vehicle’s dead weight is decreased, its overall economy improves. Composite materials made up of many polymers have found use in the automotive industry. This study’s principal purpose is to validate a sandwich architecture that can be utilized in battery housing for EVs. Which aims to design a sandwich composite structure that is 10-15% lighter than a comparable state-ofthe- art solution. This is accomplished by testing the physical and experimental characteristics of composite material for a new sandwich architecture where the core of the sandwich is made of a foam-packed 3D-printed honeycomb structure and natural fiber laminates are utilized as the sandwich structure’s face sheets. The core is 3D printed utilizing FDM technology with a lattice honeycomb structure, printed using Acrylonitrile Butadiene Styrene (ABS) thermoplastic polymer. Where a hexagonal-cell composite is less in weight and absorbs more energy than solid composites. Also, flax fiber laminate is used as a face sheet for sandwich composites. This study validated the characteristic performance of sandwich composites for the flexural test to investigate the bending behaviour of sandwich composites and was analyzed using the finite element model developed in ANSYS Workbench R2
