Title:
CONTINUOUS ELECTROPHORETIC DEPOSITION MODIFIED CARBON FIBER REINFORCED MULTI-MATRIX COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/134214
Kind Code:
A1
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.
