Abstract: Method for producing a nanocomposite material reinforced by unidirectionally oriented pre-dispersed alumina nanofibers. The process is suited for industrial-scale production of the nanocomposite materials. The nanocomposite production process involves, synthesis of unidirectionally oriented pre-dispersed alumina nanofibers, casting a mat of pre-dispersed nanofibers with a predetermined orientation in the atmosphere of air or other gas(es) by saturating the nanofibers with liquid polymer matrix. Polymer matrix may include thermosets or/and thermoplastics. The material forming the polymer matrix may be heated to its melting point temperature to transform it to liquid phase. After saturation, the polymer matrix is hardened by lowering its temperature or by means of exposing the polymer matrix to UV radiation, electron beam and/or chemical hardeners. The nanomaterial is composed of polymer composite with homogeneously dispersed uniformly oriented reinforcing nanofibers.

Abstract: A method for synthesizing monocrystalline alumina nanofibers by controlled liquid phase oxidation of a melt including molten aluminum. The method comprises two stages. During the first stage, metallic aluminum is melted and various additives are introduced into the melt. During the second stage, the alumina nanofibers are synthesized from the resulting melt in the presence of oxygen. In one or more embodiments, the inventive method is performed in a reactor. The reactor is designed to provide the heating and to enable melting of metallic aluminum. In addition, the reactor is designed to maintain a sustained temperature of between 660° C. and 1,000° C. When the additives are introduced into the molten aluminum, it is desirable to provide steady and uniform the stirring of the melt. To this end, the reactor may be provided with a stirring mechanism.
