Pressurization method of fiber prepreg tape reinforced thermoplastic composite pipe

The invention discloses a pressurization method of a fiber prepreg tape reinforced thermoplastic composite pipe. The pressurization method specifically includes the following steps that firstly, the outer portion of the reinforced thermoplastic composite pipe is wrapped by a reinforcement layer, and multiple layers of one-way fiber reinforced thermoplastic resin belts are wound around the two endsof the reinforced thermoplastic composite pipe through a winding process under the heating condition; secondly, sealing end clamp installation is conducted on the reinforced thermoplastic composite pipe through an inner sealing clamp; and thirdly, connection with a pressurization device is conducted, and pressure tests are conducted. By means of the method, the inner sealing clamp can be repeatedly used multiple times, cost is reduced, and meanwhile the composite pipe reinforcing layers can be well protected during pressurization through the outer reinforcing layers wrapped on the composite pipe so that test results
