1. An impact beam comprising a polymer matrix and a reinforcing structure, said reinforcing structure comprising a number of metal reinforcing cords and non-metal elongated binding elements or non-metal coated elongated binding elements arranged between the metal reinforcing cords for holding the metal reinforcing cords together, each of said metal reinforcing cords has a metallic cross-sectional area Ametal, the ratio φ

  • c of the metallic area Ametal to the area of the circle circumscribing said metal reinforcing cord (π

    dcord2/4) is at least 0.60, said metal reinforcing cords further having a non-chemical binding with said polymer matrix, wherein said non-metal elongated binding elements or non-metal coated elongated binding elements have a chemical bond with said polymer matrix.
