Fiber optic cable FRP Central Strength Member optical fibre cable
1. FRP (glass fiber) has the following features:
(1) Light weight, high strength
Relative density between 1.5 ~ 2.0, only 1/4 ~ 1/5 of the carbon steel, but close to the tensile strength, even more than carbon steel, and the intensity of than can be compared with the advanced alloy steel. Therefore, in the aircraft, rocket, the spacecraft, high pressure vessel, and in other applications, the need to reduce the weight of products have excellent results. Some of the tensile, bending and compression strength of epoxy FRP can reach more than 400 mpa.
(2) the corrosion resistant performance is good
FRP is good corrosion material, the atmosphere, water, and general concentration of acid, alkali, salt, and a variety of oils and solvents have a better ability to resist. Has been applied to all aspects of chemical corrosion, is replacing the carbon steel, stainless steel, wood, non-ferrous metal and so on.
(3) good performance
Is a good insulating material, used to make the insulator. Under the high frequency can still protect good dielectric properties. Microwave permeability is good, has been widely used in radome.
(4) good thermal performance
FRP low thermal conductivity, at room temperature is 1.25 ~ 1.67 kJ/(m. h. K), only 1/100 ~ 1/1000, metal is a good thermal insulation material. Under the condition of the instantaneous ultra high temperature, is the ideal thermal protection and ablation resistant material, can protect the spacecraft at above 2000 ℃ under high-speed air flow.
(5) good design
(1) can be flexibly designed, according to their needs, a variety of product structure, to satisfy the use requirement, can make the product has good integrity.
(2) can fully material selection to meet product performance, such as: you can design a decay resistance, resistance to instantaneous high temperature, products of a certain direction with a special high strength, good dielectric properties, and so on.
(6) good manufacturability
(1) according to the shape of the products, technical requirements, use and quantity to the flexibility to choose the molding process.
(2) the process is simple, can be a molding, economic effect is outstanding, especially for complex shape, not easy to shape the number of product less, more prominent its technological superiority.
