Abstract:
1. A multi-function composite material assembly for use in the lay-up of a composite part, the composite material assembly comprising: a non-cured composite material; and a multi-function detection liner comprising: a first insulative layer having a density in contrast to that of the non-cured composite material, such that the first insulative layer is detectable by ultrasound within the composite part; a first conductive layer bonded to the first insulative layer and configured to provide an eddy current signal and to enhance ultrasound attenuation of the detection liner within the composite part, the first conductive layer including a first conductive mesh; and a second conductive layer bonded to the first insulative layer and the first conductive layer, the second conductive layer including a second conductive mesh, wherein the detection liner is releasable from a surface of the non-cured composite material during the lay-up process.
