What Is Carbon Fiber ?
Choose from hundreds of manufacturing materials including various grades of thermoplastics, metals, and elastomers.
When selecting a material, consider the material properties, manufacturability characteristics, cosmetic appearance, and cost.

Carbon fiber is a super-strong yet lightweight material. It is five times stronger than steel, twice as stiff and around 1.5 times lighter.


Carbon Fiber is a polymer and is sometimes known as graphite fiber. It is a very strong material that is also very lightweight. Carbon fiber is five-times stronger than steel and twice as stiff. Though carbon fiber is stronger and stiffer than steel, it is lighter than steel; making it the ideal manufacturing material for many parts. These are just a few reasons why carbon fiber is favored by engineers and designers for manufacturing.


Fibers are bundled in various sizes designated in thousands (K) of fibers. 1K, 3K, 6K, 12K, 24K, 50K and others are common bundle sizes. These fibers are woven into fabric with various weave patterns. 3K fabric is most common. The various types of fiber will have the same “K” designation to indicate the number of fibers in the bundle. These numbers describe the size of the bundle used and have little to do with the quality of the fiber itself.

How is Carbon Fiber Made?
Carbon fiber is made of thin, strong crystalline filaments of carbon that is used to strengthen material. Carbon fiber can be thinner than a strand of human hair and gets its strength when twisted together like yarn. Then it can be woven together to form cloth and if needed to take a permanent shape, carbon fiber can be laid over a mold and coated in resin or plastic.
An Overview of The Carbon Fiber Manufacturing Process:
Carbon fiber is made from a process that is part chemical and part mechanical. It starts by drawing long strands of fibers and then heating them to a very high temperature without allowing contact to oxygen to prevent the fibers from burning. This is when the carbonization takes place, which is when the atoms inside of the fibers vibrate violently, expelling most of the non-carbon atoms. This leaves a fiber composed of long, tightly inter-locked chains of carbon atoms with only a few non-carbon atoms remaining.
A typical sequences used to form carbon fibers from polyacrylonitrile involves spinning, stabilizing, carbonizing, treating the surface and sizing.

Advantages Of Carbon Fiber :
1. Lasting Performance 2. Good Resilience 3. High Strength 4. Good Tenacity 5. High Corrosion Resistance 6. Excellent Structural Properties 7. UV Resistant Inhibited 8. Environmentally Safe 9.

Superior Dimensional Stability 16 . Smooth finish on surface


What Can Be Made With Carbon Fiber?
Almost anything. Because of its special characteristics, carbon fiber is very popular in many industries such as aerospace, automotive, military, and recreational applications.

Applications of Carbon Fibers for reference :

Chemical inertness, high corrosion resistance Chemical industry; nuclear field; valves, seals, and pump components in process plants
UV Resistant Inhibited Medical applications in prostheses, surgery and x-ray equipment, implants, tendon/ligament repair

What Carbon Fiber Grade Do We Often Use ?
Firstly, carbon fibers are divided into T and M grades. T is for strength, M is for toughness and M is for tensile strength. The highest level of the T grade is T1000 and the highest level of the M grade is MJ60 currently. The M grade is more difficult to produce than the T grade. T grade is widely used in aircraft, cars, high-grade bicycles and so on. The M grade can be used in rockets, spacecraft, satellites, etc.
According to the data of 2018, Toray T1400 has the highest T class and T1000 is the best in China currently. The mass production of T1100 in Japan and of T700-T800 in China. The M grade has the highest mass production of MJ60, as well as MJ65 and MJ70.

Most popular used carbon fiber in China is T300 ,T700 and T800 . The internal arrangement structure of the T300 T700 and T800 is different, raw material and produce processing are different, which makes a significant performance difference. So they have a difference in application areas.

At present, the production of carbon fiber products in the civilian market is mainly based on T300, which is a comprehensive consideration of cost performance.

What is T300 carbon fiber?
T300 – Baseline carbon fiber used in aerospace applications with over 20-year service history. Has 30-year production history and is known for balanced composite properties, high quality and consistency, reliability and availability of supply. Available in 1K, 3K, 6K and 12K sizes.

What is 3K carbon fiber?
3K carbon fiber is the most popular, most common carbon fiber. The plate has a classic carbon fiber look. 3K is the workhorse of carbon fiber. It's light, relatively stiff, easy to find and simple to use. 3K has higher elongation to failure and a better strength than 6K, 9K or 12K.

Krosino could supply different kinds of carbon fiber products according to customers' demands , we welcome any client's enquiry along with the specification and requests from all over the world .
