Abstract: Methods and apparatuses are provided for the production of homogeneous dispersions of nanostructures within a matrix, which may be used as precursors of carbon-reinforced or boron nitride-reinforced composite materials. An apparatus for producing a nanostructure dispersion comprises a reactor and a mixing chamber, wherein the reactor is configured to produce an aerosol of nanostructures and is in fluidic communication with the mixing chamber. A matrix material is provided in the mixing chamber, and the aerosol of nanostructures can disperse into the matrix material to form a nanostructure dispersion. The apparatus may further comprise a matrix tank comprising a matrix material, wherein the matrix material is transferred to the mixing chamber. An aerosol of matrix particles may be produced from the matrix material and provided in the mixing chamber, so as to produce a fine dispersion of nanostructures in the matrix. The apparatus may be configured to continuously produce a nanostructure dispersion.
