Carbon Fibre Yarn

Carbon Fibre Yarns from SageZander

SageZander provides high performance Carbon Fibre Yarn working as agents for Formosa Plastics on this product for many years. Our Carbon Fibre materials are suitable for a wide range of industrial applications and carbon fibre production methods.

Carbon Fibre consists of around 95% of carbon atoms and this fibrous durable material is a product of modern technology. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fibre.

The crystal alignment makes the fibre incredibly strong for its size. Several thousand carbon filaments together to form a yarn, which is often processed using resins or woven into a fabric prior to applying resins. Carbon fiber filament yarns are usually combined with other materials to form a composite material.

Carbon Fibre Applications

Woven Fabrics

We start with TC33 1.5k suitable for weaving fabrics around 100 grams per square metre weight or lower. TC 33 3k is generally for fabrics around 200 gsm where a good aesthetic carbon fibre surface is needed. The heavier weight tows can be woven as they are or can be spread and woven as tape yarns produced to create lighter weight fabrics that can be cost effective. The below shows a couple of examples of where our fabrics can be used in the automotive and information technology industries using 12k carbon fibre for wheels and 3k carbon fibre showing good aesthetic qualities for laptops.

Multiaxial fabrics - 12k and 24k Carbon Fibres

TC35R 12k and TC35R 24k carbon fibers are our most popular qualities, giving a good performance and a competitive cost structure where the fibre performance required doesn’t need to meet the typical industry standard 36 Msi and 250 Gpa. If you do need 36 Msi and 250 Gpa then our TC36P 12k and 24k carbon fibers are available. (Also see our low melt yarn page for holding threads)

Uni Directional Fabrics

Feeding our fibres in to Uni Directional prepreg fabrics is a great option, with the TC35R 12k and 24k carbon fibers being good alternatives. We have some types with low size possibilities which can help fibre spreading. Check with us about the options.

Pultruded Profiles

For general pultrusion processes such as rods, tubes and more complex grades, our general array of grades is available. For structural applications and cable core applications, our TC36P grade might be preferred for some applications. For flat laminates used as plates in wind energy applications our TC35R 48k is generally the most used option.

The length of a pultruded profile using our carbon fibre can be many kilometres long with the limitation being the amount of metres on the spools of yarn that are used in the process. Ask us if you have a need for longer spool lengths.

Filament Winding

For pressure vessels our TC36P, TC780, and TC880 in 12k or 24k carbon fibre yarn are generally the grades of choice.

Braiding Carbon Fibre

Carbon fibre yarns are also used for braiding. Because Tairyfil carbon fibre yarn does not contain any twist this can give advantages in the braiding process. The applications for braided materials can be as varied as aerospace and prosthetics. Our materials throughout the range from 1.5k to 48k all have potential in suitable applications.

We have a list of suggested applications and grades. Please let us know if we can answer any questions you have

About Carbon Fibre Manufacturing

This is our basic guide explaining the basics of carbon fibre yarn manufacturing and giving a few insights into Formosa’s activities.

Our carbon fibre is manufactured at Mailiao on the West side of Taiwan by Formosa Plastics Corporation. The manufacturing area is on land that was reclaimed from the sea, the whole site controlled by Formosa Plastics Group (FGP), the parent company. FGP is publicly listed and employs well over 100,000 people worldwide. Within the group Formosa has control over all manufacturing of the carbon fibre producing the raw materials beginning with the cracking of oil to produce the components needed to spin the precursor yarn which is eventually carbonised. Formosa use the brand name Tairyfil for their fibre.

How Is Carbon Fiber Made?

In this picture, step 1, is showing the spinning process of the acrylonitrile yarn which is extruded through spinnerets (in a similar way to nylon or polyester filaments). The filaments produced are treated in various ways on their way to being wound onto spools which will then be used for the next process. Producing the acrylonitrile yarn is a crucial part of making sure the final carbon fibre yarn and processing parameters are highly guarded. Different acrylonitrile yarns might be manufactured to achieve carbon fibres with different target properties.

Step 2 sees the acrylonitrile precursor being converted into a carbon fibre yarn. There are many parameters here that can be adapted. These can be dependant upon which thickness of carbon fibre we are working with ; i.e. 3k (3,000 filaments) or 48k (48,000 filament) or/and parameters will be set to create a standard modulus carbon fibre i.e TC35R 24k or an intermediate modulus TC42s 24k.

The oxidisation process uses a chamber which the precursor is passed through. The temperature here can be around 200-300 deg c and this is in air causing some changes to the reinforced polymer chains in the fibre. After oxidisation the fibre continues through to carbonisation. Carbonisation uses gases excluding oxygen and generally uses temperatures well in excess of 1,000 deg c for most carbon fibre grades. This step has the effect of aligning carbon atoms in the fibre to create what is now a carbon fibre.

In order to make the fibers more receptive to a sizing that is later applied to the fibers on the line, the surface treatment is a technique that is performed on the fibers. The size is essential because it promotes the carbon fiber’s bonding during later operations when pieces with good mechanical qualities are manufactured. Carbon fiber is now easier to process and handle thanks to the size. The yarn is wound into spools at the end of the operation, ready to be packaged and dispatched to clients.


Formosa is certified to produce carbon fibre according to the following certifications:

ISO 9001
AS 9100C
ISO 14001
OHSA 518001

Frequently Asked Questions

Carbon fiber is a low density material with a very high strength to weight ratio. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fibre.

The high strength capabilities of Carbon Fiber Yarn make it perfect for a number of applications and uses. 

About 90% of carbon fibers are made from a polyacrylonitrile (PAN) process. The remaining 10% are made from rayon or petroleum pitch process.

The filaments produced are treated in various ways on their way to being wound onto spools which will then be used for the next process. Producing the acrylonitrile yarn is a crucial part of making sure the final carbon fibre yarn and processing parameters are highly guarded.

Carbon Fiber is about 10 times stronger than steel and as much as 5 times lighter. Due to its superior flexibility, Carbon Fiber is the perfect substitute for older materials. 

It also makes Carbon Fiber Yarn highly useful and sought after.  

No, Carbon Fiber is not conductive when on its own. However, when paired with other properties it can be. 

The modulus of carbon fiber is typically 33 msi (228 Gpa) and its ultimate tensile strength is typically 500 ksi (3.5 Gpa).

Commercial carbon fibers possess high tensile strength (ranging from 3 to 7 GPa) and high Young’s modulus (ranging from 200 to 500 GPa).

Carbon fibers, however, can accumulate on the skin where the fibers act as a mechanical irritant, resulting in an itching sensation not unlike “fiberglass itch.” Accumulation of carbon fibers on forearms, at flexure points, and beneath clothing can cause itching.

The main properties of carbon fibers are:
  • high tensile and compressive strengths.
  • high modulus.
  • low density.
  • high chemical resistance.
  • high temperature tolerance.
  • electrically conductive.
