Abstract
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 μm 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.
Claims20
An impact beam, comprising:
- a polymer matrix;
- and
- metal cords,
- wherein the polymer matrix includes at least two layers, a first layer being present around a surface of the metal cords and a second layer being present around the first layer, and
- wherein the metal cords are bonded to the first layer of the polymer matrix so that a load can be transmitted directly between the polymer matrix and the metal cords.
