Abstract:

An approach is given to the damage region reconstruction within composite structures based on fibre optic image. According to the arrangements and the positions of the fibre optic detecting network, one may quantitatively analyse the shape of the damage region and extents in the structure. The damage extent figure obtained from interpolation of discrete reconstructional data coincides well with the backlighting outcome through semi translucent composites. The result of impact tests on laminates proves the effectiveness of this method.
