Sandwich structures are used where weight saving is critical like aircrafts, trains, motor vehicles and sports equipment. Current bumper fascias of road vehicles are generally made with Acrylonitrile Butadiene Styrene, Thermoplastic olefin elastomers or Polypropylene. With the evolution of composite plastics, a wider range of materials became useable for bumper fascias. Given the good compatibility between Polypropylene and Polyvinyl Chloride which are widely used together in a bumper, a sandwich model composed by these materials is hereby analysed for application on a car bumper fascia model in terms of stress through a finite element study when submitted to EURO-NCAP (European New Car Assessment Programme) standardized impact conditions.
