It will be. In that case, the longer the hollow body, the more difficult it is to supply the expandable synthetic resin to the portion of the hollow portion away from the opening, and the hollow portion of the long hollow body is vertically moved upward and downward. When the foamable synthetic resin is placed in such a manner as to fill the hollow portion, the foamable synthetic resin can be supplied to the entire hollow portion, but since the foamed portion below is crushed and becomes a non-uniform core material, the long composite Was unsuitable for manufacturing.

As a method of manufacturing the surface layer after manufacturing the core material first, while continuously inserting the core material into the molding die, the fibrous base material is passed through the gap between the core material and the molding die and pulled out together with the core material. It has been proposed to fill a void between the core material and the mold with a curable resin in the mold. However, it is not easy to insert the foamed synthetic resin into the molding die, and it becomes difficult to supply the foamed synthetic resin as the shape becomes complicated, so that the shape of the long composite is limited. There was a drawback that it would end up.

とができる。According to the method for producing a long composite of the present invention, an expandable synthetic resin is supplied to the hollow portion surrounded by the fiber base material and foamed in the hollow portion of the cylindrical shape, so that a uniform shape of arbitrary shape can be obtained. It is possible to obtain a core material made of synthetic resin foamed into. In order to guide the foam to be the core material to the position where the curable resin is supplied, all that is necessary is to pull out the fiber base material that constitutes the surface layer, and substantially eliminate the step of inserting the core material into the mold. Instead, the long composite can be easily manufactured by continuous manufacturing steps.
