<p>PROBLEM TO BE SOLVED: To easily add the materialistic high grade feel of a fiber reinforced resin, etc., to a plastic molding part and improve strength by laminating a prepreg on the surface of the plastic molding part and hardening the prepreg. SOLUTION: A lower mold jig 4 is arranged on a surface plate 6, and an engine cover main body 2 the surface of which is roughened by etching or mechanical grinding is set on the jig 4. A carbon fiber fabric/epoxy resin prepreg 7 is laminated on the main body 2, and an upper mold jig 5 is set on the prepreg 7. Next, a breather cloth 8 formed from a glass cloth, etc., is arranged to cover the jig 5. A vacuum bag film 9 is arranged on the cloth 8, and a sealant 10 is arranged between the film 9 and the surface plate 6. Next, a vacuum connector 11 is connected with a vacuum device to evacuate at a degree of vacuum of 550-760mmHg. This is arranged in an oven, etc., kept at 120 deg.C for 90min, and cured.</p> |
