Abstract

The invention discloses a fiber-reinforced composite material cable core, which comprises an inner glass fiber layer, an intermediate carbon fiber layer and an outer glass fiber cloth, bonded together by cured high-temperature resistant epoxy resin, and the inner glass fiber layer The glass fiber volume content is 5% to 45% of the mandrel as a whole, the carbon fiber volume content of the middle carbon fiber layer is 20% to 60% of the mandrel as a whole, and the glass fiber cloth volume content of the outer glass fiber cloth layer is 20% to 60% of the mandrel as a whole. The volume content of high temperature resistant epoxy resin is 34%-40%. The epoxy resin includes multi-component epoxy resin, curing agent, accelerator, mold release agent and resin modifier. The invention mainly uses the glass fiber with good resin wettability, moderate elastic modulus and signal transmission function as the core layer structure to reduce the internal stress of the fiber reinforced composite material cable core. The invention has the advantages of good comprehensive mechanical properties, small internal stress, good toughness, friction resistance, good splitting resistance, signal transmission function and the like.

Description

technical field [0001] The invention belongs to the field of electric power and is especially suitable for fiber-reinforced core cables. technical background [0002] Carbon fiber reinforced composite core cable is composed of internal carbon fiber composite reinforced core and outer aluminum stranded wire. Compared with traditional steel cored aluminum stranded wire, it has many advantages such as light weight, high strength, small sag, fatigue resistance, and corrosion resistance. It has developed rapidly in recent years, and has begun to be applied in the electric power field and gradually promoted. The biggest breakthrough of the carbon fiber composite core cable is to use the carbon fiber composite core rod as the reinforcing core instead of the original steel core. [0003] At present, the carbon fiber composite mandrel has outstanding mechanical properties, heat resistance, fatigue resistance, corrosion resistance, etc., but its structure is composed of an inner carb...
