Problems solved by technology

Steel fibers can enhance the strength of optical cables, but they have disadvantages such as poor corrosion resistance, strong electrical conductivity, and high density. They are prone to rust and generate induced currents, which limit the use and service life of optical cables; It overcomes the shortcomings of steel fiber such as poor corrosion resistance, strong electrical conductivity, and high density, and has the advantages of light weight and high strength, but at the same time there are disadvantages such as large bending radius, easy to break, and cannot be reused after breaking.

Abstract

The invention relates to application of non-woven tape. The non-woven tape comprises reinforced fibers, a bonding agent and a substrate, wherein the reinforced fiber is bonded to the substrate along the radial direction by the bonding agent. The method for manufacturing the non-woven tape comprises the following steps of: radially paving the reinforced fibers on the substrate, and obtaining the non-woven tape by gluing, glue-scraping, drying, rolling and cutting. The non-woven tape is applied to the manufacturing of the high-strength optical cable, and the method for manufacturing the high-strength optical cable by the non-woven tape comprises the following processes: longitudinally coating the non-woven tape on the outer part of the optical fiber by using the non-woven tape as a reinforcing core, and extruding the sheath on the outer part of the non-woven tape to obtain the high-strength optical cable. Compared with the prior art, the use of non-woven tape as the reinforcing core of the optical cable greatly improves the stretch-proof property of the optical cable and makes the mass of the optical cable in the same length more light and the pavement and use of the optical cable more convenient on the basis of the corrosion resistance of an optical cable and the like and the prominent advantages of high tensile strength and low density of the non-woven tape.

Description

technical field [0001] The invention relates to industrial materials, in particular to the application of a latitude-free tape. Background technique [0002] At present, steel fiber or glass fiber is generally used as the strengthening core of optical cable in my country. Steel fibers can enhance the strength of optical cables, but they have disadvantages such as poor corrosion resistance, strong electrical conductivity, and high density. They are prone to rust and generate induced currents, which limit the use and service life of optical cables; It overcomes the shortcomings of steel fiber such as poor corrosion resistance, strong electrical conductivity, and high density, and has the advantages of light weight and high strength. Contents of the invention [0003] The purpose of the present invention is to provide a high tensile strength, very light weight non-weft tape in order to overcome the above-mentioned defects in the prior art. [0004] A kind of object of the p...
