Embodiment Construction

[0046] Further description will be given below in conjunction with the embodiments shown in the accompanying drawings.

[0047] The continuous fiber-reinforced plastic pressure pipe shown in the accompanying drawings, the middle reinforcement layer of the pressure pipe consists of at least one axially stretched inner prepreg plastic fiber strip 3 and at least one circumferential helical (preferably helix angle is 40-89 degrees) The outer prepreg plastic fiber tape 2 covering the inner prepreg plastic fiber tape is composed of the two sides of the middle reinforcement layer, respectively, the plastic inner wall layer 4 and the plastic outer wall layer 1 which are connected with the middle reinforcement layer through extrusion molding. When the inner prepreg plastic fiber tape is manufactured, it directly bears the pulling force, so that the manufacturing can be carried out continuously.

[0048] In the above structure, the inner prepreg plastic fiber belt can be located on the ...

Abstract

The invention relates to a continuous fiber reinforced plastic pressure pipe. The invention aims to provide a continuous fiber reinforced plastic pressure pipe which has the characteristics of high mechanical strength and material saving. The invention also aims to provide a manufacturing method and a production device of the continuous fiber reinforced plastic pressure pipe. The continuous fiberreinforced plastic pressure pipe is characterized in that an intermediate reinforcing layer of the pressure pipe consists of at least one axially laid inner prepreg plastic fiber band and at least one spirally wrapped outer prepreg plastic fiber band in the circumferential direction, and the two surfaces of the intermediate reinforcing layer are respectively a plastic inner wall layer and a plastic outer wall layer which are connected with the intermediate reinforcing layer into a whole through extrusion molding.

Description

technical field [0001] The invention relates to a continuous fiber-reinforced plastic pressure pipe, in particular to a pipe composed of pre-impregnated plastic fiber tape and plastic; the invention also relates to a manufacturing method and device for the continuous fiber-reinforced plastic pressure pipe. Background technique [0002] Existing pipes made of various plastics and metal or non-metallic composite reinforcement materials are widely used in fluid transportation. In order to ensure the performance of the plastic pressure pipe, the wall thickness of the pipe must meet the requirements of internal pressure strength and ring stiffness at the same time. As a result, when producing large-diameter plastic pressure pipes, the amount of plastic raw material used is very large. The increase in wall thickness will greatly increase the amount of raw materials used, which will lead to too high manufacturing costs for the pipes to be accepted by the market. [0003] Although...
