By recycling the waste polymer material and using it in weight reduction studies of electric vehicles, a double-sided gain isachieved against environmental pollution. Sandwich structures with prismatic cores obtained by recycling waste polymerscan be used in structural applications of light and heavy commercial vehicles and public transportation vehicles that carrycargo and passengers. These sandwich vehicle parts could help to increase the max. range and load-carrying capacity ofelectric vehicles. In this study, sandwich plates with prismatic egg-box cores were produced with waste Polypropylene.Since the materials are collected from different waste sources, the physical properties (additive ratio, secondary substancedetermination, density) of the recycled material were measured. Thereafter, hardness, quasi-staticflatwise and edgewisecompression, and 3-point bending tests were done to determine the mechanical properties of the structure. After that,dynamic compression and 3-point bending tests were performed to determine the strength and impact energy absorptioncapacity of the structure in collision situations. Finally, impedance tube tests were carried out for the acoustic charac-terization, which is one of the important parameters affecting interior cabin comfort, and Sound Transmission Loss (STL)and Sound Absorption Coefficient (SAC) values of the structure were determined.
