Use of Carbon Nanotubes in Structural Composites

Carbon nanotubes (CNT) possess excellent intrinsic characteristics such as exceptionally high mechanical and conductive properties which make them the prime candidate to reinforce high-performance composite structures. However, location and dispersion state of the CNTs are of particular importance to achieve the mechanical and electrical enhancement of carbon-reinforced composites. In the frame of European Project SARISTU, different approaches were investigated by the different partners (e.g., veils, powdered doped prepreg, and doped adhesives). Each approaches required specific dispersion solution. Along its existence, Nanocyl has developed a large experience in incorporation of CNTs in different resins (thermoplastics, thermosets, etc.) using improved innovative mixing process, CNT surface modification (functionalization) or by adding some dispersing agents or compatibilizers. Applying this expertise to SARISTU context, the requested products were delivered in the suitable form for each scenario. As an example, ground CNT/thermoplastics compounds were produced for powdered doped prepreg and different grades of doped thermoplastics for veils production.
