Carbon fiber composite material is a group of high-performance materials of strategic importance. The use of composites is a growing reality in many industrial fields, from marine structures to transport industry and especially in defence components. On many industrial applications, plasma surface treatments are used for activating treatment for surfaces of various materials prior to any coating, painting or bonding. Therefore, it can also be referred to as a kind of pretreatment of surfaces. Treatment with plasma removes any contaminants present on the surface of a material making it more suitable for further processing. A vacuum plasma treatment is usually performed in a chamber or enclosure that’s evacuated. The air within the chamber or enclosure is pumped out prior to letting gas in. The gas then flows in the enclosure at a low pressure. This is done before any energy (electrical power) is applied. Vacuum plasma is a more homogeneous surface treatment than atmospheric plasma. Therefore, this method is preferred in surface adhesion problems of carbon fiber composite materials. In this study, the surface properties of the carbon fiber composite and the change of the wetting angle were investigated. The experimental results show that choosing the optimal parameters is possible to improve the wettability of composite substrates and reduce the contact angle.
