Specifications

PAN Carbon Fiber, Carbon Fiber Roving, 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
