Electrical circuit assemblies and structural components incorporating same

摘要

Composite structural components are disclosed that include electrically conducting fibers providing multiple signal or paths to electrical components disposed on or adjacent the material. The signal paths may therefore be embedded in the structural component as an intrinsic reinforcing element. Also disclosed are materials for making up the structure and fabrics and methods for the production thereof.

主权项

1. An electrical circuit assembly comprising:
spaced electrical components arranged to at least one of send and receive at least one of a control signal and a data signal, said components including digital input/output terminals for inputting/outputting the at least one control signal and data signal; two or more conducting paths for electrically coupling the components, each path including an electrically conducting fibre for conducting the at least one control signal and data signal, the electrically conducting fibre forming part of a fibre reinforced composite material having a plurality of reinforcing fibres and a matrix material wherein substantially all of said electrically conducting fibres and substantially all of said reinforcing fibres are in at least partial surface bonding contact with said matrix material, whereby said conducting fibres also serve as reinforcing fibres; means for selectively modulating one or more electrical properties of the reinforcing fibres; and a first group of electrically conducting fibres defining a conducting core spaced from a second group of electrically conducting fibres defining an electrical screen, by a third group of electrically insulating fibres, at least some of the fibres of the third group being hollow to allow an electrical property modulating material to be selectively introduced into and withdrawn from said fibres of the third group.
