Embodiment Construction

[0045] Combine below figure 1 and figure 2 , the present invention is further described:

[0046] Such as figure 1 As shown, a carbon fiber composite 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 made of heat-resistant high-mechanical performance epoxy resin and carbon fiber. Composite, the protective layer 13 is a composite 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 of curing agent; 10-30 parts by mass of diluent; accelerator of 0.5-5.0 parts by mass; filler of 0.5-5.0 parts by mass; the mixed epoxy resin includes epoxy resin a and epoxy resin b ; Epoxy resin a is a dicyclopentadiene (DCPD) type epoxy resin,...

Abstract

The invention relates to a cable core of carbon fiber composites. The cable core of the carbon fiber composites comprises a bearing core (12) and a protective layer (13), and 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 the 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 by 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, in particular to a carbon fiber composite material cable core. Background technique [0002] As a substitute for traditional steel cores, carbon fiber composite cable cores are required to have excellent mechanical properties, 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 carbon fiber composite cable core are very high. [0003] The traditional carbon fiber composite 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, ...
