Thermoplastic reinforced plastic composite pipe end boss structure and preparation method

The invention provides a thermoplastic reinforced plastic composite pipe end boss which comprises an outer pipe, a reinforcing layer, an inner pipe, an outer sleeve and a lining, a sawtooth-shaped structure is arranged on the inner surface of the outer sleeve to increase friction force, meanwhile, a sealing groove is formed to prevent a medium from leaking along a gap, the stability of a boss structure is guaranteed to the maximum extent, and the problem that leakage occurs due to the fact that a traditional buckling and pressing mode is prone to be disengaged due to the unstable state is solved; and meanwhile, in the preparation process, the lining or a substitute plays a role in supporting a thermoplastic reinforced plastic composite pipe, and the problem that the thermoplastic reinforced plastic composite pipe is prone to being damaged through the buckling and pressing process, resulting in influence on the service life is solved. 本发明提供的一种热塑性增强塑料复合管端凸台，包括有外管、增强层、内管、外套及内衬，在外套内表面设置有锯齿形结构以增大摩擦力，同时设置有密封槽避免介质沿缝
