Carbon Fiber Composite Fiber and Tow
Who spins this fiber in the United States, and in what modulus and filament count?
What it is
Continuous filament reinforcement supplied as tow, roving or yarn, sold by filament count and sized for a specific resin chemistry. The upstream product from which every other composite form is built.
- Typical dimensions
- Commonly 3K, 6K, 12K and 24K filament counts for carbon; sized to the intended matrix.
- Also known as
- tow, roving, yarn, carbon fiber, filament
