Patent Searching and Data


Document Type and Number:
Japanese Patent JPH0322314
Kind Code:
Y2
Abstract:
A method of electrochemically surface-treating carbon fibers, fibers treated by the method, and composite materials including such fibers. The method consists in positively polarizing fibers relative to a cathode in an aqueous solution of an electrolyte constituted by a weak amino base. Nitrogen-containing groups are thus fixed to the surface of the fibers thereby improving the adhesion of the fibers to the resin in a composite material constituted by carbon fibers embedded in a synthetic resin matrix.
