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.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a carbon fiber manufacturing apparatus, and more particularly to a carbon fiber manufacturing apparatus which can greatly improve the sizing quality of a carbon fiber and effectively reduce the cost of the carbon fiber production equipment and the working time.BACKGROUND OF THE INVENTION

[0002] Carbon fibers are classified into carbon fibers or graphite fibers according to their carbon contents, which have excellent mechanical properties and electrical properties and can be widely used in various applications. A conventional carbon fiber is achieved by bundling precursor fibers, such as polyacrylonitrile fibers, to form a carbon fiber precursor fiber bundle, and then the carbon fiber precursor fiber bundle is calcined (high-temperature carbonization) to form the carbon fiber.

[0003] There are various precursor fibers of carbon fibers on the market, such as rayon, poly vinyl alcohol, vinylidene chloride, polyacrylonitrile (PAN)...
