Abstract
The present invention relates to an EMF-screened plastic-organic sheet hybrid structural component, preferably a battery housing, and to its use in motor vehicles, preferably in electrically powered motor vehicles or hybrid motor vehicles, the abbreviation EMF meaning electromagnetic field(s).
Claims17
An EMF-screening structural component comprising:
- at least a first organic sheet component comprising:
- a fabric layer;
- and
- at least one of:
- carbon fibres and metal fibres embedded in a first thermoplastic;
- and
- a second polymeric component integrally connected with the first sheet component, the second polymeric component comprising at least one of:
- carbon, metal fibres, and carbon nanotubes embedded in a second polymer;
- wherein together:
- the first organic sheet component comprises a first amount of the at least one of the carbon fibres and the metal fibres, and
- the second polymeric component comprises a second amount of the least one of:
- the carbon, the metal fibres, and the carbon nanotubes sufficient to provide the structural component with a predetermined level of EMF screening and damping of 50 db in the frequency range from 100 MHz to 1 GHz in accordance with ASTM D-4935-89.

A battery housing with EMF screening, the housing comprising a shell-like form of a structural material comprising:
- at least a first shaped-organic sheet component comprising:
- a fabric layer;
- and
- at least one of:
- carbon fibres and metal fibres embedded in a first thermoplastic, wherein portions of the housing cannot be formed by shaping of the first organic layer, and
- the portions that cannot be formed by shaping of the first organic layer comprise a second polymeric component integrally connected with the first sheet component, the second polymeric component comprising at least one of:
- carbon, metal fibres, and carbon nanotubes embedded in a second polymer;
- wherein together:
- the first organic sheet component comprises a first amount of the at least one of the carbon fibres and the metal fibres, and
- the second polymeric component comprises a second amount of the least one of:
- the carbon, the metal fibres, and the carbon nanotubes sufficient to provide the structural component with a predetermined level of EMF screening and damping of 50 db in the frequency range from 100 MHz to 1 GHz in accordance with ASTM D-4935-89.
