Fiber pipe in life and industry are more widely used tools, but the types and materials of fiber pipe is actually a lot of different materials of fiber pipe is a different role and different places of use. Fiberglass tubes and carbon fiber tubes are the more common two kinds of fiber tubes, then, fiberglass tubes and carbon fiber tubes, what are their respective characteristics? Fiberglass pipe and carbon fiber pipe which is better? We want to buy how to choose, now I introduce to you.
? Fiberglass pipe and carbon fiber pipe which is better
Fiberglass pipe:
Fiberglass pipe is a thermosetting resin (usually epoxy resin) as a matrix, glass fiber as reinforcing material, pultruded. It has the advantages of corrosion resistance, friction resistance, high strength, insulation, anti-static and low friction resistance. The use of temperature range of about -40 ℃ ~ 150 ℃, if the production of better performance of the resin, can be resistant to high temperatures of 180 degrees Celsius or even higher. According to the actual needs can also use additives, flame retardant, reduce shrinkage and other functions. It is mainly used in the field of electronics and electrical engineering.
Carbon fiber tube:
Carbon fiber tube, also known as carbon tube, will be the original carbon filament pre-impregnated with resin and then pultruded or twisted into. Pultruded tube and metal tube appearance is the same, there is no grain, winding tube has a good-looking braided pattern. Depending on the winding method, it can show plain and twill patterns. Its high temperature resistance, strength, and corrosion resistance are better than fiberglass tubes, and the scope of use is wider than fiberglass tubes, which is suitable for aerospace, automobile manufacturing, sports equipment, medical equipment and other collaterals.
In comparison, carbon fiber tubes are better.
What are the characteristics of glass fiber pipe and carbon fiber pipe
Carbon fiber pipe features:
1, high tensile strength: carbon fiber strength is 6-12 times that of steel, which can reach more than 3,000mpa.
2, low density, light weight. Density is only 1/4 less than steel.
Carbon fiber tube features:
1, good corrosion resistance. Because the main raw material of FRP is made of unsaturated polyester resin and glass fiber with high molecular composition, it can effectively resist the corrosion of acid, alkali, salt and other media and the erosion of untreated sewage, corrosive soil, chemical waste water and many chemical liquids, and in general, it is able to maintain safe operation for a long time.
2, anti-aging properties and good heat resistance. Fiberglass tube can be used for a long time in the temperature range of -40 ℃ ~ 70 ℃, the use of specially formulated high-temperature resistant resin can also be above 200 ℃ temperature normal work.
3, good frost resistance. Below -20 ℃, the pipe will not freeze after freezing.
4, light weight, high strength. Relative density between 1.5 ~ 2.0, only 1/4 ~ 1/5 of carbon steel, but the tensile strength is close to, or even exceed carbon steel, while the specific strength can be compared with high-grade alloy steel. Therefore, in aviation, rockets, space vehicles, high-pressure containers, and in other products that need to reduce the weight of the application, have excellent results.
5, good designability.
Can be flexible to design a variety of structural products to meet the requirements of use, can make the product has a good integrity.
6, good abrasion resistance. The water containing a large amount of mud, sand and gravel, loaded into the tube for rotational wear impact comparison test. After 3 million rotations, the depth of wear of the inner wall of the test tube is as follows: 0.53mm with tar and enamel coated steel tube, with epoxy resin and tar coated steel tube is 0.52mm, the surface hardening treatment of the steel tube for the glass fiber reinforced plastic tube is 0.21mm. which glass fiber reinforced plastic good abrasion resistance.
7, good electrical and thermal insulation. FRP is a non-conductor, the pipe's electrical insulation is excellent, insulation resistance in 1012-1015Ω.cm, the most suitable for use in power transmission, telecommunication lines in the dense area and the mine area of the FRP heat transfer coefficient is very small, only 0.23, is five thousandths of steel, the pipe's thermal insulation performance is excellent.
8, friction resistance is small, high conveying capacity. Glass fiber reinforced plastic pipe inner wall is very smooth, roughness and friction resistance is very small. Roughness coefficient of 0.0084, while the n-value of the concrete pipe is 0.014, cast iron pipe is 0.013.
Above, I give you a detailed introduction to the fiberglass pipe and carbon fiber pipe what are the characteristics of their respective characteristics, for the fiberglass pipe and the characteristics of carbon fiber pipe for a more detailed introduction, I believe that you have a clearer understanding of the fiberglass pipe and carbon fiber pipe, right? I also feel that the fiberglass pipe and carbon fiber pipe which is better, just for the analysis of their respective advantages, and can not be generalized to say which one is good, it needs to look at which one is suitable for everyone. But the carbon fiber tube indicators are better.
