PROBLEM TO BE SOLVED: To provide a manufacturing method of FRP that can mold FRP into a complex shape with good accuracy and gives a high productivity. SOLUTION: In the method for manufacturing an FRP tank, a covering process for covering a metal core 5 by winding reinforcing fibers around it is conducted before the impregnation process for reinforcing fibers by impregnating it with a matrix resin. Subsequently a precure process for precuring the matrix resin by heating it and an aftercure process for performing the aftercure by heating the matrix resin at a temperature higher than the precure process. The core 5 consists of a metal having a melting point higher than the heating temperature at the precure process and not higher than the heating temperature of the aftercure process. In the aftercure process the core 5 is melt and poured down. COPYRIGHT: (C)2008,JPO&INPIT |
