Carbon fiber

Carbon fibers are fibers about 5 to 10 micrometers (0.00020-000039 inches) in diameter and are composed mostly of carbon atoms.

Carbon fiber has many advantages such as high strength and hardness, high tensile strength, low weight-to-strength ratio, high chemical resistance, high temperature tolerance and low thermal expansion. Carbon fiber is five times stronger and two times harder than steel.

All of these features make carbon fiber very popular in fields such as aerospace, civil engineering1, the military, and motorcycles, along with other competitive sports.

However, carbon fiber is relatively expensive compared to similar fibers such as glass fiber, basalt fiber and PVC fiber.

Carbon fiber, the continuous movement of science in the field of structural earthquake engineering, has led to the use of new methods and new materials in recent years. Among these innovations, FRP (carbon fiber reinforced polymer material) has a special place in the field of reinforcement, so much so that according to some experts, FRP should be called the building material of the third millennium.

FRP and carbon fiber composite, which was first used in the aerospace industry, with new features such as high weight resistance, corrosion resistance, fast and easy transportation and installation, a new window for civil engineers and specialists in structural strengthening and concrete building reinforcement. So today, many structures around the world have been strengthened using these materials.

Buy carbon fiber

Buy carbon fiber, you can get carbon fiber from Pikaran Sazan companies. Carbon fiber has a relatively high modulus of elasticity compared to glass fiber and Kevlar. Also, carbon fiber has a low coefficient of thermal expansion of this type of fiber at different temperatures, which makes the size of carbon fiber stable at different temperatures.

Since there is a lot of competition in the field of selling carbon fiber in the market, it is recommended that you pay special attention to its quality and price in choosing and purchasing carbon fiber, so that you are satisfied with your purchase.

How to produce carbon fiber

To produce carbon fibres, carbon atoms are bonded together in crystals lined up parallel to the long axis of the fibre. Because the crystal plane gives the fiber a higher volume-to-fiber ratio (in other words, it is stronger than its size)

Thousands of carbon fibers are bonded together to form tows that can be used alone or woven into fabric.

Carbon fiber is usually combined with other materials to form a composite. When combined with plastic and bakery resins, it produces a carbon fiber reinforced polymer (often referred to as carbon fibre) that is relatively strong in weight and extremely tough, though somewhat brittle.

Carbon fiber body:

The atomic structure of carbon fiber is similar to graphite. It consists of sheets of carbon atoms in a regular hexagonal shape (graphene sheets). But the difference lies in how these papers are linked together. Graphite is a crystalline material in which the sheets are regularly stacked in parallel.

Depending on the starting material for fiber production, carbon fibers may be turbinated, graphitic, or have a composite structure with both graphite and turbinated moieties.

In turbo carbon fibres, sheets of carbon atoms are randomly folded or crumpled.

Carbon fiber and its benefits

Carbon fiber has a very high strength-to-weight ratio – high tensile strength, very strong tensile strength by weight, carbon fiber has about one-third the weight of steel and 5 to 10 times its strength. It also has a high tensile-to-elastic modulus-to-weight ratio and accepts good fatigue strength. Carbon fiber sets it apart from other engineering materials by its extremely low coefficient of thermal expansion, light and strong composites, and heat stability. Despite the ability to weave and produce fabrics with high abrasion resistance, durability, long life against chemicals and impermeability to X-rays are the most notable characteristics of carbon fiber.

Carbon fiber application

Carbon fiber is used in various industries. Carbon fiber can be used in the aircraft industry to make delicate aircraft parts, carbon seats, some aircraft exteriors and interiors, or it can be used in the automobile industry. Carbon fiber is also used to make brake pads, steering boxes, shock absorbers, engine parts, and the body of some cars.

One of the most important uses of carbon fiber is in building construction and retrofitting. Reinforcing buildings made of carbon fiber is known as FRP reinforcement and is done to strengthen and improve the strength of buildings against events such as earthquakes.

Carbon fiber texture type

Carbon fabric is actually a form of carbon fiber, which is woven into fabric. Carbon texture is available in three types of textures, each of which has its own application and is used in specific situations.

The first type of carbon weave is the plain weave, which is also the most common weave. This fabric is dense so the carbon fabric sags a bit. The second type of textile fabric is called carbon fiber kajrah, which is used to make curved surfaces due to its high flexibility. Finally, the third type of carbon fabric weave is the unidirectional weave, which carries the weight of a large portion of the fabric in one direction.

Problems of purchasing carbon fiber in Iran

Problems of purchasing carbon fiber in Iran, in recent years due to sanctions, importing carbon fiber has encountered many difficulties. This has led some people to use similar fibers instead of carbon, the most common being glass and basalt fibres.

Unfortunately, most of the fiberglass samples used for FRP reinforcement in the country do not have any tensile strength to strengthen the structure. The main application of these fibers is in the industrial insulation, automobiles and paper industries, and because of their similarity to the glass fibers used in building reinforcement, it can only be detected by laboratory methods.

The use of basalt fibers in strengthening concrete structures has a short life. This fiber was first produced in the United States and Russia is now one of the largest producers of this fiber in the world. This fiber has been seen being used in many cases in projects due to its appearance very similar to carbon fiber and its cheap price.

It is important to note that we are only allowed to use these fibers when the designer is designing the reinforcement based on the mechanical properties of basalt in his calculations, because the tensile strength of these fibers is about half that of carbon and their elastic modulus is about one third of carbon. Due to the lack of information about this fiber available in Persian sources, we decided to provide a brief explanation about this matter.

Basalt fibers are produced by heating basalt rocks to a temperature of 1500 degrees Celsius. Basalt suitable for this purpose contains more than 46% silica and a low iron content.

The thickness of these fibers usually ranges from 10 to 20 microns, although 5 micron-thick specimens have been produced, which is a good substitute for asbestos. Uses of basalt fibers in compressed natural gas, geogrid, petroleum, automobiles, thermal insulation, wind turbines, and more recently, basalt rebar are good substitutes for steel.
