Chopped Carbon Fiber

Using chapped carbon fibers (CCF™ code) is one of the common methods of reinforcing fiber concrete or FRC. Chapped carbon fibers can increase the structural strength of concrete; Because in addition to the fact that carbon fibers are lighter than steel bars (their weight is about a quarter of the weight of steel), their resistance is also higher than steel bars. Also, these fibers are more resistant to corrosion. Due to the structure becoming lighter and also not needing a concrete cover, the structures that use these fibers are thinner. Concrete reinforced with carbon fibers is also called Carbocrete or CFRC (Carbon Fiber Reinforced Concrete).


PRODUCT DESCRIPTION

History of carbon fiber

For the first time in the 19th century, Thomas Edison used chopped carbon fibers as a bulb filament. The first industrial use of carbon fibers in the aircraft industry was in the 1980s. Currently, these fibers are used in all parts of airplanes (such as wings and fuel tanks). In the 1990s, the use of these fibers in sports expanded rapidly. The reason for the rapid growth of the use of carbon fibers in sports was due to two factors:

The price of fibers gradually decreased

The demand and need of sports to use lighter materials, to consume less energy, also increased.

Currently, the most type of composites are glass fibers (about 85%), but the use of carbon fibers is expanding rapidly.

Creating antistatic property

One of the main characteristics of carbon fibers is conductivity. In the conductive antistatic flooring system, in order to conduct and discharge static electricity, carbon fibers are used to produce antistatic lining and antistatic coating. The amount of use of carbon fibers depends on the amount of resistance and conductivity expected from conductive antistatic flooring.

Features


  •  Low length change
  • High modulus of elasticity
  •  Resistant to chemicals
  •  Small dimensions of fibers
  •  Resistant to heat
  •  Appropriate resistance in mechanical conditions
  •  Due to the lighter weight of the structure, it is more resistant to earthquakes
  •  Higher durability: due to non-corrosion of concrete. This eliminates the advantage of periodic inspection of the structure
  •  Concrete fireproofing

Applications


  • Residential buildings: concrete reinforced with carbon fibers can be used in walkways, floors and foundations.
  • Commercial: Slabs and floors and parking lots have the potential to use this type of fiber.
  • Warehouses and industrial buildings: It can be used for floors that are exposed to light to heavy loads, in floors and slabs, as well as for vehicle tracks.
  • Highways and roads: can be used in retaining walls on the side of highways and railway bridges.
  • Ports and Airports: Can be used on airport runways, taxiways and parking lots as well as seawalls.
  • Waterways: used in dams and water channels and canals.
  • Mining and tunneling: prefabricated components of tunnels such as tunnel linings and gabions are used.
  • Agriculture: This concrete can be used in the construction of grain warehouses and silos, as well as livestock preservation structures.
    Chapped carbon is the most widely used anti-static agent in epoxy flooring.

Application Instructions

The method of mixing carbon fibers and concrete:

Wet and dry methods can be used to combine carbon fibers into concrete.

Dry method:

In this method, carbon fibers should be combined with aggregates. The working method is that a part of fibers is poured on a part of aggregate, then layers of aggregate and fibers are poured on top of each other and mixed with each other by hand. Then turn on the mixer and mix the aggregates prepared in the previous section plus cement in the mixer. After this step, lubricant or water reducer should be added to the mixer. Now the mixer should be left for 5 minutes so that the components inside it are well combined. During these 5 minutes, the accelerator should be added to the water. Now water should be added to the mixer. At this stage, you should wait about 3 minutes for the mixer to combine the ingredients well. Now the concrete is ready.

wet method:

In this method, first add the accelerator to the concrete. Now the carbon fibers should be added to the water and put in the mixer until it becomes completely uniform. Then add aggregates to the mixer. Now add the water reducing additive to the mixer. At this stage, the mixer should be left for 5 minutes so that the contents are well mixed. If necessary, pour the chemical additive into the mixer and wait for 3 minutes. Now the concrete is ready.

Amount of consumption

The consumption amount of chapped carbon to make the epoxy floor antistatic
Static electricity is created due to rubbing (creating friction) between flooring and plastic materials such as shoes, wheel movement or other similar things, which will remain in the same place due to its static nature. If it is not discharged in time, it may explode There are mostly irreparable damages.
Static electricity ESD (Electro Static Discharge) must have happened to you while you walk on the carpet in the room, you reach the refrigerator, and the moment your hand comes into contact with the door of the refrigerator, you feel an electric shock. This phenomenon is the same thing. In physics, it is called ESD or (Electro Static Discharge).
One of the problems we face in the operating room is the presence of static electricity. Due to the many visits to the operating room due to the phenomenon of friction between the ground and plastic materials such as slippers or the wheels of surgical beds, static electricity is created on the ground and due to its static properties, it remains in the same place.
The presence of static electricity in the operating room, which is adjacent to anesthetic gases and high frequency devices, can bring the risk of explosion. Therefore, measures should be taken to eliminate it, including the use of antistatic and conductive shoes in the operating room. These floor coverings minimize the electrostatic charge caused by the movement of equipment and the movement of people, and their electrical resistance has also been controlled. Removing or reducing voltage and load on rubber products by creating holes and ways that disperse the load is very important in many cases. The antistatic property of any material is influenced by its electrostatic charge properties.
One of the main characteristics of carbon fibers is conductivity. In the conductive antistatic flooring system, in order to conduct and discharge static electricity, carbon fibers are used to produce antistatic lining and antistatic coating. The amount of carbon fibers used depends on the expected resistance and conductivity of the conductive antistatic flooring. Carbon fiber is the most widely used anti-static agent in epoxy flooring. Carbon fiber has a diameter of 10-15 micrometers and a length of 2-6 mm is available. The amount of carbon chapped to create antistatic properties of the floor is between 1 and 2 percent by weight. In addition, carbon fiber has advantages such as lightness, high tensile strength, low thermal expansion coefficient and high thermal resistance.
