PROBLEM TO BE SOLVED: To obtain a mold for molding an FRP molding which can achieve both of fouling recoverability and delustering. SOLUTION: Pear-skin etching for delustering, sand blasting, glass bead polishing, buffing, and plating are applied successively on the inner surface of the mold to make a fouling recovery factor at least 85%. In this way, the mold which can mold the FRP molding delustered to make the fouling recovery factor at least 85% is obtained. COPYRIGHT: (C)2008,JPO&INPIT
