NOVELTY - The method involves producing a carbon nanotube containing dispersion from 0.05-0.7% by weight based on total weight of polymeric binder comprising liquid resin, dispersing aid and optionally a viscosity reducer. The dispersion is combined with a component necessary to produce the polymeric binder to form reaction mixture. The carbon nanotube containing dispersion or reaction mixture is incorporated into fibrous material. The fibrous material is subjected to conditions such that the polymeric binder is cured.    USE - Method for producing carbon nanotube reinforced composite from polymeric binder and fibrous material for a turbine wind blade (claimed).    ADVANTAGE - The method enables providing a carbon nanotube-reinforced liquid polymer or polymer-forming system for production of large composite articles. The method allows carbon nanotube-reinforced liquid polymer or polymer-forming system to be effectively incorporated into fibrous reinforcing material by vacuum infusion process or pultrusion process. The method enables providing a carbon nanotube-reinforced composite article with the carbon nanotube-reinforced liquid polymer or polymer-forming system. The method enables production of a composite wind turbine blade. The method enables vacuum infusion of reinforcing material with the carbon nanotube-containing liquid polymer or polymer-forming system. The method enables providing carbon nanotube-reinforced composite produced by a vacuum infusion process that have sufficient green strength to be de-molded in 6 hours or less and have improved fracture toughness.    DETAILED DESCRIPTION - The polymeric binder is made of material that is selected from a group consisting of polyurethane, epoxy resin and vinyl ester. The fibrous material is selected from a group consisting of glass fiber, glass mat, carbon fiber, polyester fiber, natural fiber, aramid fiber, nylon fiber, basalt fiber and a combination of glass fiber, glass mat, carbon fiber, polyester fiber, natural fiber, aramid fiber, nylon fiber and basalt fiber. INDEPENDENT CLAIMS are also included for the following:    (1) a carbon nanotube reinforced composite    (2) a wind turbine blade.
