Abstract

The invention relates to the technology field of fiber winding and discloses a fiber winding fiber reinforced plastic pipeline structure and a sand inclusion layer manufacturing method and device. The fiber winding fiber reinforced plastic pipeline structure comprises an inside liner, a structural layer and an outer protection layer. The structural layer comprises an outer winding layer, a sand inclusion layer and an inner winding layer. The inner winding layer and the outer winding layer are formed by dipping glass fibers through resin glue in a composite mode. The sand inclusion layer is formed by winding pocket abrasive cloth and fiber yarn on quartz sand dipped with the resin glue. By means of a fiber winding fiber reinforced plastic pipeline provided by the invention, the adsorption force of the sand inclusion layer and the interlayer binding force and the interlayer strength of the wall of the pipe are improved, and the flexibility, the tensile strength and the rigidity are improved.

Description

technical field [0001] The invention relates to the technical field of fiber winding, in particular to a fiber-winding fiberglass pipe structure, a method and a device for manufacturing a sand layer. Background technique [0002] At present, there are three processes for the production of glass steel pipes in my country, namely continuous manufacturing method, fixed-length manufacturing method and centrifugal casting process. Among them, the production line of fixed-length winding pipe is a semi-automatic production equipment, the stability of product quality mainly depends on the proficiency of the operator, the production efficiency is low, and the sanding of fixed-length winding pipe adopts the sand wrapping process, that is, glass fiber The cloth wraps the quartz sand inside. Because the sand layer is isolated and helpless, the source of the resin used to infiltrate the quartz sand is the glass fiber cloth. When the fiberglass cloth is wound, the extrusion itself impregn...
