Carbon fiber yarn/ carbon roving/ carbon product

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
