Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Such as Figure 1-8 shown.

[0033] A high-strength composite stranded wire with a trapezoidal cross-section, which can be divided into 7 single strands ( image 3 ), 13 single strands ( Figure 4 ), 19 single structures ( Figure 5 ), and 7 strands ( Image 6 ), 19 shares ( Figure 7 ) or 43 shares ( Figure 8 ) structure of multi-strand composite strand structure, figure 1 Lines 1-3 in the middle correspond to 7, 13, and 19 strands of single-strand composite material strands, and rows 4, 5, and 6 respectively correspond to multi-strand composite strands of 7 strands, 19 strands, and 43 strands. In specific implementation, the single-strand composite material core wire can be surrounded by a cylindrical core wire 1 and several (6 single-layer, 12 second-layer, 18 third-layer) around the cylindrical core wire 1. The cross-section aroun...

Abstract

The invention discloses a high-strength composite stranded wire with a trapezoidal section and a one-step preparation method thereof. The high-strength composite stranded wire is formed by stranding at least one composite core wire, and is characterized in that the composite core wire consists of a cylindrical core wire, and a plurality of trapezoidal stranded wires surrounding the cylindrical core wire and having trapezoidal sections; the surface of each trapezoidal stranded wire is wound with a layer of unidirectional or bidirectional fiber; the trapezoidal stranded wires surround the cylindrical core wire for stranding, with the stranding angle of 6-12 degrees and the pitch of 120-180mm; the cylindrical core wire is formed by sticking a plurality of carbon fibers through a cylindrical hole mould; and each trapezoidal stranded wire is formed by sticking a plurality of carbon fibers through a trapezoidal hole mould. The high-strength composite stranded wire has the advantages of large effective section area and high bearing capability.

Description

technical field [0001] The invention relates to a composite material cable and its preparation method, in particular to a trapezoidal composite material stranded wire capable of increasing the section of the stranded wire and its preparation method, in particular to a high-strength composite material stranded wire with a trapezoidal cross section and a one-step method of preparation. Background technique [0002] Because carbon fiber has the advantages of high strength and good corrosion resistance, composite cables made of carbon fiber have been widely used in bridges and buildings. The current carbon fiber cables are all twisted by a plurality of cylindrical core wires, and a large amount of binder is filled between the cylindrical core wires, which leads to the failure of the effective cross-sectional area of ​​the cable, thus making the cable Therefore, designing a new type of cable with large effective cross-sectional area and high load-bearing capacity is the key ...
