- Anti-corrosion properties
Overview
Carbon fiber yarn is supplied as continuous tow in T300 3K/6K and T700 12K formats, where the number indicates the count of filaments in each bundle. T300 grades offer dependable standard-modulus performance, while T700 12K provides higher strength, giving designers a range of options for weaving, braiding, filament winding, and direct structural reinforcement.
The yarn is the building block for woven fabrics and is also used directly in filament winding of pipes, pressure vessels, and shafts, as well as in textile and conductive applications. Its high tensile strength and anti-corrosion properties make it valuable for construction reinforcement, where carbon tow replaces or supplements steel without the risk of rust.
Delivered in 20kg rolls, the yarn integrates into automated winding and weaving equipment and pairs with epoxy and other thermoset resins. It is the foundational format for manufacturers producing their own carbon reinforcements or building wound and braided structures.

Frequently Asked Questions
What do 3K, 6K, and 12K mean for carbon yarn?
The number refers to how many individual filaments are bundled in each tow: 3K is 3,000 filaments, 6K is 6,000, and 12K is 12,000. Higher counts generally build up thickness and strength faster during weaving or winding.
What is the difference between T300 and T700 grades?
T300 is a standard-modulus grade offering reliable general-purpose performance, while T700 provides higher tensile strength for more demanding structural applications.
What are the main uses for carbon fiber yarn?
It is used for weaving fabrics, filament winding of pipes and pressure vessels, braiding, textile applications, and construction reinforcement where its strength and corrosion resistance are advantageous.
