A multi-function detection liner is applied to a non-cured composite material at the point of manufacturing for building a composite part. The detection liner includes a first insulative layer and a first conductive layer. The detection liner is configured to be detectable from a plurality of non-destructive inspection tests. The first insulative layer is detectable by ultrasound and radiograph within the composite part. The first conductive layer is configured to provide an eddy current signal and to enhance ultrasound attenuation of the detection liner within the composite part. Alternatively, the detection liner may include an integrated layer that combines the functions of an insulative layer and a conductive layer. The detection liner is releasably bonded to a surface of the non-cured composite material.
