Carbon fiber yarn
1. Introducing
Carbon fiber yarn is new reinforcement fiber, including both carbon feature and fiber limpness or machinability. It is crystallite graphite material after GF organic fiber carbonizing and graphite dealing, such as polyacrylonitrile carbon fiber and asphalt carbon fiber.

2. Producing progress
Fiber spinning
Preliminary heat treatment in oxidizing
Carbonizing
Graphite dealing
Chemical changing: Dehydrogenation, cyclizing, preliminary heat treatment in oxidizing

3. Feature
3 times Young Modulus more than fiberglass
High corrosion resistance
High strength material
Specific gravity is less 1/4 of steel
Tensile strength is more than 3500 Mpa
Modulus elasticity is 230-430 Gpa
Good heat conduction and electrical conductivity
Little coefficient of thermal expansion
Lower density
Good X radial permeability
