るハイブリッドな薄板が構成されるものである。The present invention shows that reinforcing materials made of alkali-resistant glass fiber mesh, Kevlar fiber mesh, and carbon fiber mesh have high performance in terms of toughness in the plastic region and crack restraint as shown in (-1 (h) in Figure 6). This was proposed based on the fact that the steel mesh, which is a stress material, of the ferrocement board is reinforced with the alkali-resistant glass fiber mesh, Kevlar fiber mesh, and carbon fiber mesh. By taking advantage of the rigidity in the initial elastic region, a hybrid thin plate is constructed that increases the toughness in the plastic region and has the ability to restrain cracks.
以下本発明を図示の実施例について説明する。The present invention will be described below with reference to the illustrated embodiments.
