体１を得る。 The method for manufacturing the molded body 1 will be briefly described below with reference to FIG. That is, a molded material 2 of thermoplastic synthetic resin in the shape of a seamless pipe is extruded from a mold 9 of an extrusion molding machine 7, and immediately after being extruded from the mold 9, it is heated to a high temperature (approximately 150°C to 250°C) and flexible. A continuous fiber bundle is formed by aligning a large number of long fibers in the longitudinal direction of the molding material and impregnating thermosetting liquid foamable resin between the long fibers in the hollow part of the molding material in the state. Immediately thereafter, the molding material 2 is fed into the molding passage 1.
0, and in the molding passage 10, the liquid foamable resin is foamed to fill the cavity with the foam, and the reinforcing long fibrous material is expanded into the cavity of the molding material by the foaming action of the liquid foamable resin. A molded body 1 as shown in FIG. 1 is obtained by dispersing the molded material toward the periphery and curing the molded material and foam.

The present invention adopts a configuration in which the parts near the outer skin, which are most advantageous in terms of the reinforcing effect of the long fibrous material, are intensively reinforced. (almost as reinforced as when the fibrous material is evenly dispersed in the foam).
このようなことから、長繊維状体の存在しない
空洞部の中央部分における発泡体の発泡倍率を周

こととなる。 Therefore, in the conventional molded product (the molded product disclosed in Japanese Patent Publication No. 48-30138), it is necessary to tightly integrate the reinforcing long fibrous material uniformly dispersed within the cavity with the foam. Compared to conventional molded products, which have had to keep the expansion ratio of the foam to a relatively low value, the molded products can be made even lighter and have improved insulation properties, as well as the amount of liquid foamable resin used. Therefore, it is possible to expect a reduction in manufacturing costs.
