ELECTRICAL CIRCUIT ASSEMBLIES AND STRUCTURAL COMPONENTS INCORPORATING SAME
摘要
A structural health monitoring arrangement comprises a component (panel 30) formed of fibre reinforced composite material with a plurality of electrical conducting fibres (conductors 32) intrinsic to the composite defining electrical paths that run through the composite. The paths act as sensing paths running through the material and a detector watches for changes in electrical property indicative of a structural (8x8 array of LEDs 36) event. The paths may be configured as an open or a closed node grid whose electrical continuity is monitored directly or indirectly. Alternatively they may be fibres having a piezoresi stive property and the changes in resistance may be monitored.
