Description

The present invention relates to a method for manufacturing a carbon fiber reinforced plastic and a laminated carbon fiber reinforced plastic, characterized in that a binder resin is used to facilitate lamination.

Carbon fiber reinforced plastic formed by combining carbon fiber and resin is a lightweight material that replaces metal, and is used for aerospace, sports and leisure products, wind power blades, medical devices, electronic products, automobile parts, and reinforcement materials for construction and civil engineering structures. The amount of use is increasing significantly for purposes.

In order to expand the application market of parts made of carbon fiber reinforced plastics, it is necessary to reduce the manufacturing cost of carbon fiber reinforced plastics by using recycled carbon fibers, and to develop technology for mass production of high strength carbon fiber reinforced plastic parts.

However, in the case of recycled carbon fiber, it is not easy to manufacture carbon fiber reinforced plastic parts again because the shape is not uniform. Therefore, in order to manufacture a part using carbon fiber reinforced plastic, it is essential to manufacture it in the form of a non-woven intermediate material or long fiber.

On the other hand, the physical properties of the carbon fiber reinforced plastic are affected not only by the performance of the carbon fiber and the resin, but also by the interfacial properties of both, and thus various surface treatments are required on the carbon fiber to improve adhesion with the resin. That is, since the bonding property between the resin and the carbon fiber may be a problem, desired properties can be obtained only by improving the bonding property by performing surface treatment of the carbon fiber according to the type of resin.

Therefore, the inventors of the present invention are researching a method and apparatus for manufacturing a carbon fiber reinforced plastic that can satisfy the above-described form and properties. When manufacturing a carbon fiber reinforced plastic using a roll-to-roll process, simply laminated carbon It was discovered that fiber-reinforced plastics could be produced, and the present invention was completed.
