Non-metal reinforcement member

Abstract

This invention relates to a kind of nonmetal reinforcement, it is composed of high strength gauze, the felt layer and the plastic layer. The high strength gauze and the felt layer are in the plastic layer, the high strength gauze is between the felt layer, the cross section of the reinforcement is circle or ellipse, the thickness of the plastic layer is 0.2mm-120mm, the high strength gauze is the line or net has at least one section of fiber glass, aryl gauze, PBO (Poly-para-benzoquinone benzodiazole) or at least one fiber glass, aryl gauze, PBO (Poly-para-benzoquinone benzodiazole). This invention can reach the high stretch-proof request to the nonmetal optical fiber cable in exist technology in the situation that not increase even reduce the size of exist optical fiber cable, so it can save the cost of optical fiber cable, save the space, solves the idea that people want to solve but never gain success.

Description

technical field [0001] The invention relates to a strengthening material for optical cables, in particular to a non-metallic strengthening member for optical cables. Background technique [0002] In the prior art, non-metallic optical cables usually use rigid cylindrical FRP (glass fiber reinforced plastics) and non-metallic reinforcement strips as their reinforcements. With the continuous development of the business, therefore, it is required that the optical cable can bear enough tensile force, so that the optical cable can be used on the adjacent iron tower or pole of the specified span. Due to the current limitation of the tensile modulus of FRP, for this reason, the optical cable Manufacturers have to increase the size of the reinforcement, or add additional reinforcement layers such as external fibers and aramids outside the core of the optical cable. In this way, the outer diameter of the optical cable is virtually increased, and the material consumption of the optica...

[0002] In the prior art, non-metallic optical cables usually use rigid cylindrical FRP (glass fiber reinforced plastics) and non-metallic reinforcement strips as their reinforcements. With the continuous development of the business, therefore, it is required that the optical cable can bear enough tensile force, so that the optical cable can be used on the adjacent iron tower or pole of the specified span. Due to the current limitation of the tensile modulus of FRP, for this reason, the optical cable Manufacturers have to increase the size of the reinforcement, or add additional reinforcement layers such as external fibers and fangluns outside the cable core, so that the outer diameter of the cable is virtually increased, and the material consumption of the cable is increased.
