Abstract

A zero-degree fibre winding method for making the glass fibre reinforced plastic pipe includes such steps as winding the non-woven fabric and glass fibres, which have been immersed in resin, respectively on the surface of formwork from its lower part in tangent direction, winding the unidirectional or latticed glass fibre close is same mode, spraying resin, winding annular fibre layer, adding sand, and repeating the steps 2 and 3.

Description

technical field

[0001] The invention relates to a zero-degree fiber winding method for a glass fiber reinforced plastic pipe, in particular to a zero-degree fiber winding method for a glass fiber reinforced plastic pipe using glass fiber unidirectional cloth or grid cloth. Background technique

[0002] FRP pipe is a kind of composite material pipe, which is made of glass fiber and resin pre-impregnated and then wound in multiple layers on the surface of the mold. At present, the commonly used winding system is to use the winding device on the walking trolley which is arranged on the workbench and can move along the length of the workbench to introduce the resin-impregnated glass fiber from the tangential direction of the lower part of the FRP pipe mold rotating towards the workbench. , and make it wrap layer by layer on the surface of the mold until the thickness of the structural layer and surface layer required by the pipeline is reached. The winding procedure is usually ...
