For example, the cross-sectional shapes shown in FIGS. Core material shown in FIGS. 4 and 5
The cross-sectional shape of (2) is wavy and zigzag, respectively.
The strength of the molded product (1) can be increased more than in the case of the embodiment shown in FIG. The width of the molded body (1) is, for example, 100 m
If it is more than m, depending on the mode shown in FIG. 3, the core material (2)
Since the slit through which the core passes is bent by the resin pressure in the mold, it becomes difficult to insert the core material (2) into the mold. In this case, it is preferable to divide the core material (2) as shown in FIG. 6, and the linear expansion coefficient, the secondary shrinkage ratio and the formability of the molded body according to this embodiment are different from those of the embodiment shown in FIG. There is no inferiority. When the width of the molded body (1) is 100 mm or more and the thickness is 10 mm or less, under the condition that the total width of the split core materials (2) is 50% or more of half of the peripheral length of the molded body. It is preferable to insert the core material into the mold from the viewpoint of reducing the linear expansion coefficient and the secondary shrinkage ratio. In the case of the embodiment shown in FIG. 6, different kinds of core materials, for example, glass cloth and steel paper or glass cloth and carbon fiber cloth can be inserted. It is possible to appropriately reinforce the degree.

It is solved by overlapping in two layers near the center of (1). The width of the two-layer portion is usually about 5 to 10 mm from the viewpoint of physical properties of the molded product and cost.
In this case, the thickness of the two-layer molded body (1) may be 20 to 50% thicker than the peripheral thickness.
