Carbon fiber composite rope core forming process and composite rope core manufacturing device

Abstract

The invention discloses a carbon fiber composite rope core forming process, which includes the steps of preheating / etching, dipping, single-strand preforming, winding preforming, preliminary curing, overmolding, deep curing, traction and winding, and the like. The invention also discloses a composite rope core manufacturing device, which consists of fiber creel, fiber preheating / etching device, resin impregnation tank, single-strand preforming mold, rope core preforming mold, preliminary curing device, surface It is composed of insulating layer covering device, deep curing device, traction device and winding device. The method of the invention is simple, the equipment structure is set reasonably, and the composite rope core can be formed at one time, which avoids the breakage of the single-strand carbon fiber composite core during the production of the two processes, greatly reduces the occurrence of mold blocking, and greatly improves the production efficiency of the rope. Production efficiency, reducing production costs.

Description

technical field [0001] The invention relates to a composite braided rope forming process and manufacturing device, in particular to a fiber composite rope forming process and manufacturing device, which is applied in the technical field of power transmission wires. Background technique [0002] So far, the overhead conductors used in various countries in the world are mainly aluminum-steel conductors, and there are few major innovations in the field of overhead conductors. Small flow, prone to corrosion and corona, and low tensile strength, prone to power supply line failure when used in extreme weather conditions. Therefore, according to the designability of composite materials, some people propose to replace the steel core with a carbon fiber composite core with high tensile strength, and take advantage of the low specific gravity and high strength of the composite material. This carbon fiber composite core cable has caused a major breakthrough in the field of overhead con...

[0002] So far, the overhead conductors used in various countries in the world are mainly aluminum-steel conductors, and there are few major innovations in the field of overhead conductors. Small flow, prone to corrosion and corona, and low tensile strength, prone to power line failures when used in extreme weather conditions

Therefore, according to the designability of composite materials, some people propose to replace the steel core with a carbon fiber composite core with high tensile strength, and take advantage of the low specific gravity and high strength of the composite material. This carbon fiber composite core cable has caused a major breakthrough in the field of overhead conductors However, this single composite core cable also has defects. This composite core is sensitive to surface defects. Once cracks and other defects appear on the surface, it will cause catastrophic fracture of the composite core, causing the wire to fall to the ground, which brings great danger to life safety. Large threat, while affecting the power supply line, for this reason need to reduce the occurrence of such breakage

The carbon fiber composite rope core is made of multiple small mandrels after winding and combining, which can be used to replace a single carbon fiber composite core, which greatly improves the safety performance, but there is still a lack of molding process and manufacturing of this carbon fiber composite rope core. device
