Fixed length winding technology refers to on the pipe mould of certain length, adopting spiral winding and / or hoop winding technology to manufacture pipe material layer by layer from inside to outside in the pipe mould length. Continuous winding is a kind of production method that resin, continuous fiber, chopped fiber and quartz sand are continuously layered according to certain requirements by hoop winding method on the continuously output mould, and the pipe material product of certain length is cut after solidification.
[0003] Fixed length winding technology, continuous winding technology two kinds of manufacturing technology and the product made by them have advantages and disadvantages. Fixed length winding technology is relatively simple and flexible, and the equipment price is far lower than that of continuous winding technology and centrifugal casting technology, but the interlayer performance of its product is worse than that of continuous winding glass steel pipe and centrifugal casting glass steel pipe. Traditional fixed length winding technology adopts spiral winding and hoop winding combination method, and winds layer by layer from inside to outside, and there is a very clear boundary between layers, and the interlayer performance of short fiber layer is poor, and interface delamination damage occurs when bending deformation is large. And the glass steel pipe wall made by continuous winding technology has a large amount of short fiber, and there is no obvious interlayer interface, and the bending deformation resistance is strong, but the equipment and process are relatively complex, and the flexibility is poor.
