The technology growth of carbon nanotubes on the surface of fiber by catalytic vapor deposition is now fairly well controlled at the level of research laboratories and some applications are already under consideration at industrial level. These nanomaterials have an industrial interest by improving mechanical, electrical and thermal composite properties. But industry remains the stumbing block concerning the safe use of this type of hybrid fiber. Indeed so far there is no guarantee to preserve the totality of carbon nanotubes on the surface of the fiber during its implementation (weaving, impregnation). PROCOM therefore seeks to develop a continuous surface treatment in these nanotubes to keep them on the fibre while retaining the initial properties of the hybrid fiber. The surface treatment will include an original concept of tracer combined with its detection system in order to monitor the quality of manufacturing and inspection in the process of being implemented. The development imagined in PROCOM is a continuous manufacturing process controlled from the original fiber to fiber hybrid surface treated. The pilot developed will be implemented on a chain to show pre-industrial level of maturity
