The main feature of carbon yarn is its high specific tensile strength relative to its own weight. Products reinforced with carbon fiber retain the highest known tensile strength, and in terms of material consumption and total weight, they are more profitable than steel commonly used today.

The most notable feature of carbon fiber is its extremely high adsorption capacity. The benefits of using carbon fiber reinforcement can prevent natural impurities, dyes, and solvents from entering the air. At the same time, the adsorption capacity is absolutely harmless to the carbon fiber itself.

Benefits of using carbon fiber

Generally, two properties of carbon fiber are of interest to architecture. The first type-structured multi-faceted reinforcement material-is used to make the material have higher hardness and compressive strength. The structure is reinforced with 5-10 µm thick fibers of different lengths. It is meaningful to structurally strengthen the decorative surface and supporting structure of the building.

The second goal of carbon fiber in the construction industry-embedded reinforcement-is achieved through additional processed primary fibers, which take the form of canvas, roving, thread, rope and rods reinforced with polymer resins. In this case, the carbon fiber will not strengthen the core itself as a whole, but provide it with a reliable, tear-resistant foundation.

But what are the benefits of carbon fiber? Why choose carbon fiber instead of rare metals? Let's start with the fact that in terms of physical and chemical properties, the closest competitor to carbon fiber is glass fiber, which is quite common in the form of internally plastered glass fiber. However, glass has much lower tear resistance and greater weight, while carbon polymer is not only strong, but also adheres better to surrounding solid materials due to its inherent high adhesion.

Use carbon fiber

By adding carbon fiber to the liquid filler composition, the load-bearing elements of prefabricated buildings on site or in factories can be reinforced. Carbon fiber can now be purchased in large quantities to reduce the thickness of walls, columns and other concrete structural elements that bear vertical axial compressive stress. Therefore, a lot of space is freed up for structural or structural insulation.

This kind of material will be particularly interesting for the pile foundation enthusiasts whose carbon fiber work is completely visible. Taking into account all the recommended safety margins, the compressive strength of the pillar is maintained at 12 to 15 tons, and its thickness is about 80 mm. There are only two strands of polymer reinforcement inside, while the carbon fiber roving is located on the other two sides.

How much carbon fiber is needed to reinforce concrete? It never only accounts for 0.05-0.12% of the quality of finished concrete. When it comes to hydraulic structures or concrete roof trusses, the concentration is even higher.

External structural reinforcement system

The structure reinforced with carbon fiber is very strong and can even be used as a wraparound reinforcement for heavy-duty structures. From high-rise residential buildings to prefabricated frame structures, external reinforcement strips provide unprecedented resistance to operational overloads.

Most importantly, the core of the unit itself (containing the embedded steel bars) is cast as usual, but the concrete protection layer on the sides is minimal. After removing the formwork, the product (whether it is a cylinder or a reinforcement tape) is wrapped with a layer of carbon cloth or thick thread, and then poured into fiber-containing sand concrete. This method eliminates the need to use heavy granite concrete with full strength characteristics. Moreover, even the smallest carbon-reinforced concrete layer can significantly reduce the corrosion of embedded reinforcement materials.
