More Information
Summary:PURPOSE:To provide a silicon-containing carbon fiber having excellent dispersibility in cement matrix and extremely high fixability to cement matrix and capable of easily giving a CFRC having high fiber-reinforcing efficiency. CONSTITUTION:An aqueous solution of a polymeric compound composed of an aromatic sulfonic acid or its salt bonded through methylene-type bond is incorporated with 0.04-4.0wt.% (based on the polymeric compound in the solution) of fine silica particles and, as necessary, a spinning assistant to obtain a spinning dope. The objective carbon fiber is produced by spinning the dope and carbonizing the obtained precursor fiber by heat treatment.
