Problems solved by technology

In this processing method, when the composite core is stranded, the unhardened resin in the semi-cured single-strand composite core penetrates from the inside of the cladding layer, and the resins of adjacent side strands wet each other and stay in the core strand. In the gap with the side strands, after secondary heating and curing, the adjacent strands are bonded and integrated, so that the composite core as a whole becomes a very hard rod, and as a result, the twisted wire structure should have been damaged. sex

Embodiment Construction

[0009] The stranded composite core includes a single-layer stranded composite core and a multi-layer stranded composite core; except for the most central composite core strand, the rest are stranded by a fiber-reinforced resin-based composite core strand with a spiral shape Fiber-reinforced resin-based composite core strands consist of a composite core located in the inner layer and 1 to 3 buffer layers covered by the outer layer; the composite core is composed of one or more fibers and thermosetting resin or thermoplastic resin embedded in the fiber . The buffer layer is mainly a fiber filament or fiber tape with a certain degree of flexibility and a temperature resistance level higher than 120°C. The covering method may be braided, wrapped, or longitudinally wrapped. Since it is in a semi-cured state before covering, it is in a rotating state. After curing the mold, there will be thermosetting resin or thermoplastic resin exuding from the composite core to the buffer layer u...

Abstract

The invention discloses a stranding type combined core. The stranding type combined core comprises a single-layer stranding type combined core and a multi-layer stranding type combined core which are both formed by stranding spiral fiber reinforced resin based combined core strands; each fiber reinforced resin based combined core strand comprises an inner combined core, and 4 to 6 buffering layers wrapping the outside; each combined core is composed of one or a plurality of fibers and thermosetting resin or thermoplastic resin embedded into the fibers; each buffering layer is composed of wrapped fibers or fiber belts and thermosetting resin or thermoplastic resin embedded into the fibers or fiber belts. According to the stranding type combined core, the fiber reinforced resin based combined core strands and strand blocks at all layers can be avoided adhering, so that the bending performance is outstanding.

Description

technical field [0001] The present invention relates to a stranded composite core. Background technique [0002] Resin-based high-strength continuous fiber composite wire, because of its light weight, high tensile strength, high temperature resistance, high specific modulus, and small linear expansion coefficient, should be used in power transmission, marine operations, and bridge reinforcement. widespread attention of the people. In particular, many companies headed by American CTC Company and Far East Composite Technology Co., Ltd. have increasingly highlighted the advantages of using composite materials in power transmission lines. At present, the domestic single-strand rod-shaped composite core technology is relatively mature, but the single-strand rod-shaped composite core has the disadvantages of poor bending performance and relatively low safety and reliability in the application process. Its application is limited when it is used in long-span areas that require hig...
