Abstract:

One of the most important factors affecting the characteristics of carbon fiber supplements composite materials is the interfacing resistance between carbon fiber/polymers. Carbon life implemented surface modifications play an important role in improving interface characteristics. In this study, first carbon fiber was passed through the chemical oxidation process and silan modification, then carbon fiber supplemented epoxy-based prepregles were produced. The characteristics of the composite plates obtained from the prepreg were then studied by various characterization methods. The chemical processing applied to the surface of carbon fiber has created additional connectivity areas with epoxy by increasing the functional groups containing oxygen on the surface of fiber. The silan modification has created a protective coating on the fiber surface, significantly increasing the fiber processability and the fiber/polymer attachment properties.
