Embodiment 1
[0035] A kind of composite pipe, this composite pipe comprises reinforcing material layer, inner liner and outer protection layer, and pipe inner diameter is 150mm, the thickness of inner liner is 11.5mm, the thickness of reinforcement material layer is 6.4mm, and the thickness of outer protection layer is 7.5mm. The reinforcement layer contains fiber-reinforced prepreg, inside the reinforcement layer there is an inner liner made of polyethylene, and outside the reinforcement layer there is an outer protective layer made of nylon. The fiber reinforced prepreg contains 4 parts by weight of epoxy resin and 6 parts by weight of carbon fiber.
[0036] The method for manufacturing the above-mentioned composite pipe includes the following steps: use a winding machine to hoop-wind the fiber fabric thermoplastic prepreg on the inner liner polyethylene, and wrap the outer protective layer nylon on the fiber fabric thermoplastic prepreg tape.
[0037] Coil the composite pipe and lay it...
