High-strength fiber composite cable and manufacturing method thereof

Abstract

The invention provides a high-strength fiber composite material cable and its manufacturing method, which fully impregnates thermoplastic resin into high-strength fiber bundles without impairing mechanical strength. A high-strength fiber composite cable (1) is produced by impregnating a matrix resin (3) into a bundle of carbon fibers (2). The matrix resin (3) is an oligomer with a weight average molecular weight lower than 10,000 obtained by mixing an organic compound with a phenolic hydroxyl group and an organic compound with a glycidyl ether group in a thermoplastic resin such as polyphenylene sulfide made of resin.

Description

technical field [0001] The invention relates to a high-strength fiber composite material cable and a manufacturing method thereof. Background technique [0002] The high-strength fiber composite material cable produced by bundling many long high-strength fibers and impregnating them with resin has high tensile strength, low stretchability, light weight, and excellent corrosion resistance , Therefore, it is being widely used in bridges, concrete structures, power lines, etc. [0003] As the resin impregnated into the fiber bundle, thermoplastic resins are attracting attention from the viewpoint of mass productivity and the like (for example, Patent Document 1). [0004] Thermoplastic resins have lower fluidity when melted than thermosetting resins, and are less likely to impregnate fiber bundles. When the impregnation of the thermoplastic resin is insufficient, the fibers are cut or entangled, the arrangement of the fibers is disturbed, and the surface of the cable becomes ...

AI Technical Summary

Problems solved by technology

However, exudation (a phenomenon in which the plasticizer floats to the surface over time) tends to occur, which leads to poor adhesion when high-strength fiber composite cables are used as reinforcement materials such as concrete structures
