Problems solved by technology

[0004] Some production methods also try to realize the axial arrangement of fibers: artificially arrange unidirectional fiber cloth, which has low production efficiency and the artificially arranged axial fiber tension is uneven; mechanically arrange short fibers so that the fiber direction is consistent with the axis In this way, although the mechanized arrangement of axial fibers is realized, the overall tensile strength of the short fibers is low, and the overall quality of the pipeline cannot be improved.

Embodiment Construction

[0019] The arrangement of the continuous axial fiber bands with an angle of zero to the axial direction of the pipe is preferably arranged in such a way that the width of the continuous axial fiber bands is reciprocally arranged to be a multiple of π value or π value, because the circumference of a circle=π×diameter, such continuous The axial fiber bands can evenly cover the circumferential surface of the mold without overlap and leakage between the fiber bands.

[0020] The specific implementation of the equipment is: the main shaft 1 of the winding machine is driven by a frequency conversion motor and connected to the computer control system 9; the main shaft 1 of the winding machine is locked together with the mold 4 in the form of a female and a female, and can be rotated and disassembled at the same time to facilitate the mold. The walking trolley 2 has a rolling shaft that moves smoothly on the working platform 3; the pressure roller 10 that provides fiber tension is conn...

Abstract

An arrangement method of the continuous axial fiber and the special device is about the fiber which winds the glass steel tube. In the process of the glass steel tube, the continuous axial fibrous zone is arranged out of the pipe except the toroidal fiber, so the tension direction of the fiber is same as the axial stress of the pipe instead of the reciprocal cross winding, so it can solve the problem of the axial low strength of the pipe and it improves the production efficient by the special production device.

Description

Technical field: [0001] The invention relates to a production method of fiber-wound FRP pipes in the field of building materials and general mechanical equipment for realizing the method. technical background: [0002] At present, the design theory of fiber winding to produce FRP pipes is "grid theory", which uses hoop fibers to bear the hoop stress of the pipe, and uses the grid formed by reciprocating cross winding to bear the combined stress of hoop stress and axial stress. , the angle formed by the fiber and the axial direction of the pipe in the cross-winding is determined by the pre-assumed stress ratio of the hoop and the axial direction, generally 57.5°; in the pipe structure, the fiber is the main carrier of the force, and the source of the strength of the fiber Due to its tensile strength, there is always a certain angle between the fibers arranged in reciprocating cross-winding and the axial direction, so that the advantages of high-strength fibers under tension c...
