[Prior Art] In the field of materials engineering, the most important solid materials are currently in four categories: metals, ceramics, plastics, composites? Among them, the composite material is one of the most developed, the most widely used, and the best in performance. Because it has the advantages of not being material, it is different from the general material, for example, the performance can be given to the range of the phase of the spring, which can be given to the editor. The great elasticity can be made by the same process as the general materials. However, the inner surface of the conventional composite structural member is only filled with a guar material, for example, as shown in FIG. 1, the PU foam material 1 〇〇 is used as a core material, and the fiber woven fabric is coated on the upper surface, and the outer mold is applied. 103 and the lower die 1〇1.
