A kind of glass fiber reinforced plastic cable conduit and its processing technology

Abstract

The invention discloses a glass fiber reinforced plastic cable guide and its processing technology, which belongs to the technical field of cable guides. A plurality of axial fibers arranged in the axial direction are annularly distributed on the outer wall of the inner sheath, and are distributed along the inner sheath. The transverse fiber is sheathed on the outside of multiple axial fibers in a ring, and the transverse fiber is spirally wound on the outside of the inner sheath, which plays a role in positioning the multiple axial fibers. The axial and transverse strength of the inner sheath is enhanced by the combination of the horizontal fiber, and the inner layer reinforcement and the outer sheath are respectively set on the inner and outer ends of the inner sheath. The inner layer reinforcement not only further improves the strength of the inner sheath. The axial strength of the sleeve, combined with the multi-layer stacked structure, effectively improves the overall mechanical strength of the cable guide, and also improves the heat resistance, corrosion resistance and aging resistance of the cable guide to a certain extent. The inner cable plays a very good protective role.

Description

technical field [0001] The invention relates to the technical field of cable ducts, and more particularly, to a glass fiber reinforced plastic cable duct and a processing technology thereof. Background technique [0002] Fiberglass reinforced plastic conduit is a lightweight, high-strength, corrosion-resistant non-metallic conduit. It is a glass fiber with resin matrix weight that is wound on a rotating mandrel layer by layer according to the process requirements, and quartz sand is evenly spread between the fibers as a sand layer. The design of the tube wall structure is reasonable and advanced, which can give full play to the role of the material. Under the premise of meeting the strength of use, the rigidity is improved, and the stability and reliability of the product are guaranteed. Glass fiber reinforced plastic conduit is accepted by the majority of users due to its excellent chemical corrosion resistance, light weight and high strength, no scaling, strong shock resi...

Problems solved by technology

In the prior art, the hoop winding method is often used to continuously lay layers and cut into a certain length of pipe products after curing. This leads to insufficient axial strength of the cable guide, which is easy to cause damage during construction and use. Catheter break
