Abstract:

A composite structure is fabricated from fiber-reinforced tape, segments of the tape being stacked one upon another so as to form a plurality of plies. A boron fiber is positioned adjacent to or along an edge of each of the tape segments. Because of the X-ray opacity of the boron fibers tungsten boride core and because the boron fiber will break when a ply is damaged, damage to the composite structure can be detected by radiographic examination.
