Embodiment Construction

[0049] Combine below figure 1 with figure 2 , To further explain the present invention:

[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 wrapped on the outside of the load-bearing core 12 through a winding process. The load-bearing core 12 is a composite of heat-resistant and high-mechanical epoxy resin and carbon fiber. The protective layer 13 is a composite of high-temperature and weather-resistant epoxy resin and glass fiber; the heat-resistant and high-mechanical epoxy resin of the load-bearing core 12 is made of the following components: 100 parts by mass of mixed epoxy resin; 20-75 mass parts Parts of curing agent; 10-30 parts by mass of diluent; 0.5-5.0 parts by mass of accelerator; 0.5-5.0 parts by mass of filler; the mixed epoxy resin includes epoxy resin a and epoxy resin b; Resin a is dicyclopentadiene (DCPD) epoxy resin, epoxy resin b is a combination of glycidylamine epoxy resin a...

Abstract

The invention relates to a cable core which comprises a bearing core (12) and a protective layer (13). The protective layer (13) covers the outer portion of the bearing core (12) through a winding process. The cable core is characterized in that the bearing core (12) is a composite of epoxy resin and carbon fibers, wherein the epoxy resin is heat resisting and high in mechanical property, and the protective layer (13) is the composite of epoxy resin and glass fibers, wherein the epoxy resin is high temperature resisting and weather resisting. Due to the fact that the bearing core and the protective layer are chosen to be different epoxy resin systems, the high mechanical property of the epoxy resin system of the bearing core cannot be influenced the epoxy resin system of the outer protective layer, the good weather resisting property of the outer protective layer protects the bearing core from being damaged by outer environment, and the combination property of the cable core is greatly improved.

Description

Technical field [0001] The invention relates to a cable core. Background technique [0002] As an alternative to 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 outdoor high temperature, sunlight, 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 material on the outside. Both share the same resin system. In the same resin system, the properties of high temperature resistance, tensile strength, flexural strength, modulus, compressive strength, UV resistance, and aging resistance affect each other. It is often sacrificed to increase certain aspects of performance through modifica...
