An impact beam having a polymer matrix and a metal reinforcing structure, the metal reinforcing structure including metal cords that can be made from metal elements having a diameter of 100 mum or more. The polymer matrix can include a thermoplastic material and/or a fiber material, and the metal can be steel, and the metal cords can be parallel to each other. The polymer matrix can include two or more layers that can be made from the same or different material, one of which can be positioned around the surface of the metal cords and can have a mechanical bond with the cord. The invention also includes a method of making the impact beam.
