0-'/'C [Effects of the Invention] According to the present invention, since the buffer material is provided at the interface between the reinforcing material and the surface material, durability is significantly improved. In particular, by setting the expansion coefficient of the cushioning material between that of the reinforcing material and the surface material to the same level as that of the reinforcing material, it is possible to prevent the occurrence of cracks due to temperature differences, and this has the effect of improving durability.
尚、緩衝材の膨張係数は水性分散液により可変できる。Note that the expansion coefficient of the buffer material can be varied by changing the aqueous dispersion.
