Fiber-reinforced composite material pipe and preparation method
The invention discloses a fiber-reinforced composite material pipe and a preparation method. The fiber-reinforced composite material pipe includes a core layer and an externally constraint FRP pipe, wherein the core layer is filled inside the externally constraint FRP pipe, and the core layer is formed by mixing and solidifying small and short FRP pipes, concrete and water. According to the fiber-reinforced composite pipe and the preparation method, the outer surfaces of the small and short FRP pipes becomes rough or scratches are formed in the outer surfaces of the small and short FRP pipes by grinding, sandblasting or scoring methods, the bonding force between the small and short FRP pipes and the concrete is enhanced by using a principle similar to the principle of ribbed steel reinforced bonding and slipping, the small and short FRP pipes and the concrete can better stressed in a coordinated mode, the hollow FRP small and short pipes are light in weight and low in density, the damping under the action of earthquake is higher than ordinary concrete, so that the energy dissipation capacity is good, and the externally constraint FRP pipe can further improve the concrete deformability.
一种纤维增强复合材料管及制备方法。纤维增强复合材料管包括芯层和外部约束FRP管；其中，所述的芯层填充在外部约束FRP管的内部，由FRP小短管、混凝土和水混合后固化而形成。本发明提供的纤维增强复合材料管及制备方法是通过打磨、喷砂或刻痕的方式使FRP小短管外表面呈粗糙状或形成划痕，类似带肋钢筋增强粘结滑移的原理来增强其与混凝土之间的粘结力，可更好地协同受力，并且空FRP小短管质量轻，密度低，在地震作用下阻尼比普通混凝土高，有很好的耗能能力，外部约束FRP管又可进一步提高混凝土变形能力。
