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).
Claims11
EMF-screened hybrid structural component, which ensures screening and damping of >50 db in the frequency range from 100 MHz to 1 GHz in accordance with ASTM D-4935-89, characterized in that this
- a) consists of an organic sheet component which, in turn, is built up from a woven fabric or laid fabric in a plurality of layers made of a fibrous filler, into which, in addition, carbon fibres or metal fibres are also incorporated, this woven fabric or laid fabric being embedded in a thermoplastic, and
- b) additionally consists of a further plastic component which has a high electrical conductivity which is expressed by a volume resistance of up to 103 Ωcm to ISO 3915 and a surface resistance of up to 103 Ω to IEC 60093, in that, based on 100% by volume of total filler content of the plastic component, carbon, metal fibres or carbon nanotubes are added in the range from 0.1-30% by volume, the total filler content lying in the range from 0.1-50% by volume, based on 100% plastic component.
Use of a hybrid structural component which
- a) consists of an organic sheet component which, in turn, is built up from a woven fabric or laid fabric in a plurality of layers made of a fibrous filler, into which, in addition, carbon fibres or metal fibres are also incorporated, this woven fabric or laid fabric being embedded in a thermoplastic, and
- b) additionally consists of a further plastic component, preferably of a thermoplastic, which has a high electrical conductivity which is expressed by a volume resistance of up to 103 Ωcm to ISO 3915 and a surface resistance of up to 103 Ω to IEC 60093, in that, based on 100% by volume of total filler content of the plastic component, carbon, metal fibres or carbon nanotubes are added in the range from 0.1-30% by volume, the total filler content lying in the range from 0.1-50% by volume, based on 100% plastic component,
- for screening electromagnetic fields (EMF).
