Carbon fibers

Carbon fiber is a filament of fibers that is obtained from heating excellent materials, the bulk of which is carbon in an ineffective gas environment. Carbon fibers are fibers that contain at least 90% carbon and are obtained from controlled pyrolysis of special fibers. Carbon fiber is black, non-solvent in water and odorless, which has a high resistance to corrosive substances such as acids, base and excellent materials. These fibers are available in a single direction where carbon fiber is parallel to zero degree and bi-directional alignment in which carbon fiber is located in two directions of zero and perpendicular to it (90 degrees). Carbon fiber is used in a variety of fields, such as building retrofitting, defense industry, automobile manufacturing, and many other important industries. Fibers that are made in  Carbon fiber (CFPs) is commonly used by elements such as epoxy resin to be added to the elements and members of the porter in the structures and improves the shear, bending and axial capacity of the members. 

Advantages of CARBON FIBER AND CFRP Carbon Fiber

1.Low carbon fiber weight

2.High tensile strength of carbon fiber

3.Higher elastic coefficient than glass fibers

4.Low thermal expansion coefficient of carbon fiber that keeps carbon fiber length constant at different temperatures

5.High carbon fiber resistance to corrosive substances

6.Non-explosion of carbon fiber

7.Merbene fiber strength against fatigue

Carbon fiber production sources 

 
1.Plants and Cellulose

2.Bitumen

3.Polyacryl nitrile

Disadvantages of carbon fibers

1. Carbon is an electrical conductor, which causes short circuit in non-insulated parts

2. Low impact resistance of carbon fibers against sudden impact

3. The price of carbon fibers

4. Strain in defeat

5. Due to the limited length change (about 0.1) the fibers are considered crispy

Application of carbon fibers in civil and construction industry

 
1. Retrofitting buildings and strengthening structures

2.Manufacturing and producing all kinds of plates

3.With these fibers, the strength of concrete can be increased several times

4. Carbon fibers are used in the inner glaze of most tunnels

5.Using these fibers in buildings can build light walls with high resistance 

6.Construction of pre-tanned structures

Application of carbon fibers in medicine

 
1.Making all kinds of artificial bones

2.Manufacturing and manufacturing all kinds of medical equipment parts

3.Manufacturing a variety of artificial body parts

4.Making different types of wheelchairs

Application of carbon fibers in sport

 
1.Making all kinds of rockets

2.Construction of bows and arrows

3.Manufacturing all sports equipment
