A cold drawn carbon steel filament has a surface with traces of bismuth. The steel filament can be used as a sawing wire or as part of a steel cord. During its manufacturing the steel filament has been subjected to a controlled cooling by bringing the steel filament in contact with bismuth. Bismuth may replace lead without harming the environment.

Steel filament patented in bismuth

An impact beam as subject of the invention comprises a polymer matrix and a metal reinforcing structure for impact reinforcement, which metal reinforcing structure comprises at least one woven fabric. The woven fabric comprises metal cords being essentially parallel to each other, and the metal cords are bond to the polymer matrix, so that a load can be transmitted directly between the polymer matrix and the metal cords.

Reinforced impact beam with woven fabric

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 &#x3bc;m 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.
