Abstract

The invention relates to a carbon fiber composite material cable core, which comprises a load bearing core (12) and a protection layer (13), wherein the protection layer (13) is covered outside the load bearing core (12) through a winding process, the load bearing core (12) is a high-temperature-resistance mechanical property epoxy resin and carbon fiber compound, and the protection layer (13) is a compound of high-temperature-resistance and weather-resistance epoxy resin compositions and glass fibers. The carbon fiber composite material cable core adopts the blending epoxy resin of the hydantoin epoxy resin and low-viscosity epoxy resin as resin substrates, the requirement of glass fibers on the low viscosity of the resin can be met, and the cable core can also have excellent high-temperature-resistance performance.

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 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, UV resistance, and agin...
