Abstract

A continuous electrophoretic deposition modified carbon fiber reinforced multi-matrix composite material, composed of 30-55% by volume fraction of carbon fiber, 3-25% by volume fraction of inorganic powder, and 20-67% by volume fraction of a matrix, the inorganic powder being wrapped on the surface of the carbon fiber or being embedded in a carbon fiber bundle, and the concentration being gradually reduced from a fiber filament to the surface of the fiber bundle. A preparation method for the continuous electrophoretic deposition modified carbon fiber reinforced multi-matrix composite material comprise the steps of: pretreating carbon fiber; preparing slurry of inorganic powder; widening the pretreated carbon fiber to form a carbon fiber strip, and then performing electrophoretic deposition on the inorganic powder; preparing a preform from the deposited carbon fiber; and compounding a matrix in the preform. Uniform deposition of the inorganic powder on the surface of the carbon fiber filament is guaranteed by widening treatment of the carbon fiber, the deposition efficiency is improved, and the performance and the stability of the composite material are improved.

Abstract

The present disclosure discloses a continuous electrophoretic deposition modified carbon fiber reinforced multi-matrix composite and a preparation method thereof, composing of a carbon fiber with a volume fraction of 30-55%, an inorganic powder with a volume fraction of 3-25% and a matrix with a volume fraction of 20-67%, wherein the inorganic powder is wrapped on the surface of the carbon fiber filament or embedded in the carbon fiber bundle, and the concentration gradually decreases from the fiber filament to the surface of the fiber bundle. The preparation method of the composite is as follows: (1) pretreating the carbon fibers; (2) preparing a slurry of the inorganic powder; (3) widening the pretreated carbon fiber to form a carbon fiber strip, and then carrying out electrophoretic deposition on the inorganic powders; (4) preparing a preform from the deposited carbon fibers; and (5) compounding a matrix in the preform.
