Embodiment Construction

[0049] Combine below figure 1 with figure 2 , the present invention is further described:

[0050] Such as figure 1 As shown, a cable core includes a load-bearing core 12 and a protective layer 13. The protective layer 13 is coated on the outside of the load-bearing core 12 through a winding process. The load-bearing core 12 is a composite of heat-resistant high-mechanical performance epoxy resin and carbon fiber. The protective layer 13 is a compound of high temperature and weather resistance epoxy resin and glass fiber; the heat-resistant high-mechanical performance epoxy resin of the load-bearing core 12 is made of the following components: 100 parts by mass of mixed epoxy resin; 20-75 parts by mass The curing agent of part; The diluent of 10-30 mass part; The accelerator of 0.5-5.0 mass part; The filler of 0.5-5.0 mass part; Described mixed epoxy resin comprises epoxy resin a and epoxy resin b; Resin a is a dicyclopentadiene (DCPD) type epoxy resin, and epoxy resin b i...

Abstract

The invention relates to a manufacture method of a cable core. The manufacture cost of the cable core comprises the following steps: carbon fibers are led out of a creel, gum dipping is carried out to the carbon fibers after entering a first gum dipping area, and used epoxy resin is epoxy resin with heat-resisting high mechanical property; the carbon fibers after gum dipping enter a first curing oven to be precured, carbon fiber composite core are manufactured, the diameter of each carbon fiber composite core is 5mm to 12mm, and a curing degree reaches more than 85% by adjusting temperature; glass fibers on two sides are led out and respectively enter a second gum dipping area and a third gum dipping area, and used epoxy resin is high temperature resistant and weather resistant; the glass fibers after gum dipping pass through a winding area and are wound and cover the outer layers of the carbon fiber cores, the thickness of single side is 0.5mm to 2mm, and winding speed is synchronous with pultrusion speed by being controlled by a servo motor; and the carbon fiber composite cores and the glass fiber protective layers pass through the second curing oven after being compounded, and are fully cured by adjusting temperature. Composite material cable core products pass through a dragger and are wound up on the position of a winding disc.

Description

technical field [0001] The invention relates to a cable core, in particular to a manufacturing method of the cable core. Background technique [0002] As a substitute for traditional steel cores, cable cores are required to have excellent mechanical properties as well as high temperature resistance, UV resistance, and aging resistance due to long-term work in harsh conditions such as high temperature in the field, sunshine, and climate change. The comprehensive performance requirements of the core are very high. [0003] The traditional cable core structure is a load-bearing core made of carbon fiber and epoxy resin composite material inside, and a protective layer made of glass fiber and epoxy resin composite outside, both of which share the same resin system. Under the same resin system, properties such as high temperature resistance, tensile strength, flexural strength, modulus, compressive strength, UV resistance, and aging resistance affect each other. Increasing a cer...
