[0025] The present invention will be described in detail below in conjunction with the examples.
[0026] A kind of FRP pipeline production process of the present invention, described FRP pipeline is formed outside the FRP mandrel, comprises the following steps:
[0027] S0: FRP mandrel preparation: The FRP mandrel is connected with a driving device that drives it to rotate along the axial direction, as long as it can achieve uniform rotation. During the laying process of each fiber layer, the FRP mandrel is in a state of uniform rotation.
[0028] Base layer preparation: Spray wear-resistant resin evenly on the surface of the FRP mandrel.
[0029] Reinforcement fiber preparation: Arrange the reinforcement fibers neatly on both sides of the axis direction of the FRP mandrel. When arranging, the fiber creel can be used for placement, and the fiber creel slides along the axis parallel to the FRP mandrel.
[0030] Preparation of resin glue: choose resin glue with pouring mechan...
