View the Complete Application at the US Patent & Trademark Office
Carbon nanotube-reinforced composites are produced by incorporating up to 0.7% by weight of carbon nanotubes into a liquid polymeric material a polymeric material. The viscosity of the carbon nanotube-containing liquid polymeric is sufficiently low that it can be used in vacuum infusion and pultrusion processes to produce large articles such as wind turbine blades.
