Characteristics of the FRP pipe.

Characteristics of the FRP pipe.

(1) FRP pipe light weight and high strength relative density in 1. 5 to 2.0, only 1/4~1/5 of carbon steel, but the tensile strength is close, even more than carbon steel, and the specific strength can be compared with advanced alloy steel. Therefore, in aviation, rockets, spacecraft, high-pressure vessels and other products need to reduce the weight of the application, have excellent results. Some epoxy FRP tensile, bending and compressive strength can reach more than 400Mpa. Part of the material density, strength and specific strength are shown in Table 1-1.

(2) good corrosion resistance FRP is a good corrosion-resistant material, the atmosphere, water and general concentration of acids, bases, salts and a variety of oils and solvents have good resistance. Has been applied to all aspects of chemical corrosion, is replacing carbon steel, stainless steel, wood, non-ferrous metals.

(3)good electrical properties is an excellent insulating material, used to make insulators. Good dielectric properties can still be protected at high frequencies. Microwave transmission is good, has been widely used in radar antenna cover.
(4) good thermal performance FRP pipe low thermal conductivity, at room temperature for 1.5MPA. 25~1.67 kJ/(m·h·K), the only metal of 1/100~1/1000, is the excellent insulation material. In the instantaneous ultra-high temperature conditions, is the ideal thermal protection and ablation-resistant material, to protect the spacecraft above 2000℃withstand high-speed air scouring.
(5)Good Design can be needed, the flexibility to design a variety of structural products to meet the requirements, you can make the product has good integrity.② You can fully select materials to meet the performance of the product, such as you can design a corrosion-resistant, instantaneous high temperature, there is a direction on the product particularly high strength, good dielectric properties, and so on.
(6)excellent workmanship ① can according to The Shape of the product, technical requirements, use and quantity to the flexibility to choose the molding process.② The process is simple, can be a molding, prominent economic effect, especially for complex shapes, a small number of difficult molding products, more prominent its technological superiority.
