A kind of carbon fiber composite cable with optical fiber and preparation method thereof

Abstract

The invention discloses a carbon fiber composite cable with optical fibers, which comprises, sequentially from inside to outside, optical fibers with a metal sleeve, an interface layer made of a carbon fiber woven sleeve reinforced thermoplastic resin composite material, an anti-seismic layer made of carbon fiber woven sleeve reinforced thermoplastic thermosetting composite resin, and a carbon fiber unidirectional composite wire layer. The invention further discloses a preparation method of the carbon fiber composite cable with optical fibers. By combining the carbon fiber woven thermoplastic interface layer and metal sleeve surface modification technologies, the metal sleeve surface and the carbon fiber composite material form interface combination with good infiltration in the optical fiber embedding process. The optical fiber structure is firmly fixed through weaving with carbon fibers, and the problem of inconcentricity caused by optical fiber slippage in the subsequent compositing process is avoided. The thermoplastic / thermosetting composite resin anti-seismic layer ensures the anti-seismic and anti-bending properties of the whole composite cable in the winding and unwinding processes.

Description

technical field [0001] The invention belongs to the field of power transmission and power communication, and in particular relates to a carbon fiber composite cable with an optical fiber and a preparation method thereof. Background technique [0002] With the development of modern industry, the power system has higher and higher requirements for communication, not only telephone communication, but also large-capacity information transmission that can accommodate remote control, telemetry, data transmission, etc., especially the automatic control and tracking detection of many power equipment The use of computers has greatly increased the amount of transmitted information. In the past, many researchers have adopted the composite structure of communication cables and overhead power cables to solve the above requirements, but due to the problem of communication interference of various processes, this research has been stagnant. [0003] Since the appearance of optical communic...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many researches focusing on the composite technology of carbon fiber composite cable core material and optical fiber, but there are still many structural instabilities in the composite cable of this new structure: ①The optical fiber material is composited with the carbon fiber composite cable. Tension winding is also required during the process, so direct use will inevitably cause damage to the optical fiber; ②The traditional metal protective sleeve on the surface of the optical fiber and the composite molding of the carbon fiber composite cable bring about the weakness of the interface material mismatch. ; ③ The optical fiber / metal sleeve composite material itself has a large specific gravity and poor flexibility, so it is difficult to solve the problem of embedding concentricity in the preparation process of composite cables
