As the novel technologies regarding the new generation of fuel transportation and stocking are emerging, the filament winding process appears to be a promising fabrication technique for creating reliable pressure vessels that incorporate a pre-impregnated reinforcing structure. The same method can be applied to any axial symmetric component such as tubes, tow bars and generally tubular composite structures. While the composite filaments are being wound, many factors may influence several parameters that are directly related to the overall mechanical performance of the structure, such as voids in resin-reach areas, variation of the filament angle in values outside of the ones desired, and gaps between subsequent filaments placed together. In the present work, an experimental study is presented in which the potential of a vision system is exploited for detecting such kind of defects that are formed in filament winded tubes. This kind of systems may be used for optical inspection and quality control, as well as for monitoring the component during the process. Gaps between filaments and the winding angle are retrieved after scanning the tubes and several observations are presented about the variation of them throughout the length of the tube.
