Carbon fiber manufacturing apparatus

Abstract

A carbon fiber manufacturing apparatus includes a feeding module, a high-temperature carbonization module, a plasma surface treatment module, a sizing module, and a receiving module. A carbon fiber precursor fiber bundle released from the feeding module is sequentially processed at a predetermined speed to perform high-temperature carbonization, plasma surface treatment, sizing, and so on. The carbon fiber precursor fiber bundle is heated to form a carbon fiber, and then the surface of the carbon fiber is coated with a resin oiling agent. Particularly, through the plasma surface treatment module, the surface of the carbon fiber is roughened and provided with functional groups, which is beneficial to enhance the interface bonding of the resin oiling agent and the carbon fiber. The structure of the carbon fiber is more stable and reliable. The cost of the carbon fiber production equipment and the working time can be reduced effectively.
