Summary: | The invention relates to a method for preparing a curved FRP (Fiber Reinforced Plastic) pipe. The method comprises the following steps: 1) customizing a curved core mold; 2) winding and wrapping the impregnated cloth on the curve core mold at a certain rotating angle with the axis of the curve core mold; (3) the impregnated cloth is evenly coated with forming resin, after the forming resin is cured and formed, the obtained pipe fitting is placed in a demolding pool, and demolding is carried out through a melting curve core mold; (4) the curve type FRP pipe obtained after demolding is placed in a cleaning pool to be soaked and cleaned; and 5) putting the soaked and cleaned curve-shaped FRP pipe into a rinsing pool for rinsing, fishing out and airing to obtain the curve-shaped FRP pipe. According to the method, the needed curve type FRP pipe is rapidly and temporarily prepared by fully utilizing the plasticity of the impregnated fabric and the foamed plastic, the construction progress can be effectively acceler |
