Continuous electrophoretic deposition modified carbon fiber reinforced multi-matrix composite and preparation method thereof
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 2 0 -6 7 %, 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. In the present disclosure, uniform deposition of inorganic powder on the surfaces of the carbon fibers is guaranteed through widening treatment of the carbon fibers, the deposition efficiency is remarkably improved, the multifunctional characteristic of the composite is improved, and the performance and the stability of the composite are remarkably improved.
