Carbon fibers in concrete have high hardness and resistance and are usually ineffective against chemicals. Carbon fibers are filaments formed by heating organic materials in an inert gas environment. They are composed of approximately 90% carbon, and are formed by controlled pyrolysis. Black carbon fibers do not dissolve in water, have no odor, and have a very high resistance to harmful substances. Corrosive such as acids, bases and acids.
Carbon fiber is used to strengthen buildings, automobile manufacturing, and other industries. The fibers used in carbon fiber construction strengthen structures. Carbon fiber in concrete has high heat resistance which makes it a non-explosive fiber for this material due to its lightness and high resistance. In other industries such as seismic improvement of buildings, FRP composite is also used.
Carbon fibers in concrete are characterized by very light weight and very high tensile strength, and these fibers are considered one of the most widely used fibers in industries such as composite materials and reinforcement. Carbon fiber is used to make car carbon armor, engine parts, racing car bodies, automobile carbon fuel tanks, steering boxes, and shock absorbers. Fibers are also used in other industries such as the medical industry, energy sector and aviation industry.
Carbon composite and concrete
Carbon fiber in concrete has a high modulus of elasticity, and its use in cases such as: reinforcement and improvement can be very practical, and the modulus of elasticity of carbon fiber can be said to be higher than other FRP fibers. These fibers have high fatigue resistance and, as mentioned above, carbon fibers have high tensile strength.
If your buildings or structures are damaged under any conditions such as earthquakes or other situations, you can use carbon fiber in order to make it safe and create favorable conditions, which is one of the FRP reinforcement compounds.
Composed of two components, carbon polymers and a matrix, carbon fibers in carbon composites are stronger than traditional materials such as steel and are approximately 70% lighter than steel. The polymers found in carbon fiber are materials commonly used in the reinforcement industry. These polymers are usually made of carbon and are glued to the building and structures in the form of fabrics and make the structure flexible and resistant.
These compounds have thermal and electrical conductivity and also have low density. Carbon and carbon composites have many uses, one of which is its use in the aviation industry.
Why is it used in concrete?
Carbon fiber has high tensile strength, and carbon fiber concrete has very high strength and elasticity. Adding fibers to concrete leads to the formation of homogeneous materials in it. When concrete cracks, the fibers in the concrete increase in the formed cracks, and this factor increases the strength and flexibility of the concrete.
Carbon is usually produced and manufactured from plant cellulose, bitumen and polyacrylonitrile. Carbon fibers are created from organic bases that form fibres. If you want the carbon fiber to have good properties, you should use the core fiber in the manufacture of carbon fiber which has the greatest amount of directivity. It is one of the best types of fibers to make. Carbon fiber is an acrylic fiber that contains 55% carbon in its structure.

How is carbon fiber reinforced concrete made?
Carbon fiber reinforced concrete is considered one of the most important building materials that is increasingly being used in almost all regions of the world. This concrete is carbon fiber reinforced concrete and is one of the newest types of flexible, curve-resistant concrete. It is used to strengthen the walls of structures.
Concrete covers various applications such as building infrastructure and has features such as the ability to be easily used in any shape and form. Concrete also has unfavorable properties. Such as low tensile strength and crack resistance, but an important feature of this concrete is its longevity which is a very important point.
The use of carbon fibers today is considered very effective in improving the performance of concrete for buildings and structures. The fibers are short, thin strands with high tensile strength.
conclusion
According to what was said in the above text, carbon fiber has high resistance, and because of its good features in aviation industries, it is used in the concrete fiber industry. This fiber has high resistance and very good elasticity, and almost compared to other fibers, it has a higher price and resistance to chemicals.
