PURPOSE:To provide a method for molding and cutting easily a molded body into a defined length after the molded body passes through a mold when a composite consisting of a core material layer made of a metal, etc., and a fiber-reinforced resin layer formed around the core material layer is molded by means of pultrusion molding method and to provide the composite obtd. thereby. CONSTITUTION:As shown in the figure, a core material 1 with a hollow and ring crosssection and made of a metal is used and a plurality of these core material 1 are made of a easily cuttable raw material and have the same crosssectional shape and the both ends are connected in the molding direction by using a joint which can connect end parts of the core material 1 and when it is cut into a defined length after performing pultrusion, if cutting is performed at the position of the joint 2 by means of a cutter 9, the cutting work is easily performed. In addition, pieces of the joint which are other divided parts of the joint 2 remain on both end parts of the obtd. composite and they exhibits a function sealing the end parts of the core material made of a metal and the obtd. composite 10 can be used as it is not only for a structural material but for a pipe material. |
