Natural fibers have garnered significant interest from both industry and researchers for their environmentally friendly properties and contribution to sustainable practices. This study investigates the thermo-structural performance of a car dashboard made from natural fiber-reinforced polymer composites (NFRP), focusing on scenarios where the vehicle is parked directly under sunlight. Exposure to such conditions may affect the dashboard’s functionality due to the thermal loads experienced. A numerical simulation was performed to analyze solar radiation and passenger compartment air duct airflow affect the dashboard's temperature, tension, and structural deformation. The NFRP composite, with natural fibers as reinforcement and epoxy resin as the matrix, exhibited a minor temperature gradient under these conditions. The material's performance was evaluated using mechanical tests, which included tensile and bending tests, carried out using a universal testing machine (UTM). The results were compared to conventional dashboard materials, highlighting the potential of NFRP composites in automotive applications.
