PURPOSE:To shorten the curing time of a molding material of FRP by installing a heat pipe inside a mold body. CONSTITUTION:Blocking plates 5 are connected continuously to both ends of an external cylinder 3 in a mold body 1, the noses of the plates 5 are coupled continuously with the end sections of the outsides of an internal cylinder 2, and a sealing chamber (a) is formed between the internal cylinder 2 and the external cylinder 3. A wick 8 is stretched into the sealing chamber (a), and a working fluid is sealed, thus constituting a heat pipe. After the molding material of FRP is wound on the outer surface of the external cylinder 3, the mold body 1 is admitted into a curing oven, then the blocking plates 5 are heated. The working fluid vaporized in the sealing chamber (a) is condensed by the wick 8, and flows to the sections of the blocking plates 5 while latent heat is given to the external cylinder 3. Accordingly, the molding material of FRP wound on the external cylinder 3 is heated not only from the outer surface but also from the inside.
