The Acylation of Carbon Fiber Surface and Its Graft Polymerization with Polyamide 6 Ⅰ.The Grafting Methods and Mechanical Property of CF/PA6 Composites
Abstract:
Chemical groups (-COOH, -OH) on carbon fiber surface were transformed into CF-COCl, which was used as an effective activating group for graft polymerization of MC nylon 6 onto carbon fiber surface. The morphology of the graft nylon 6 on carbon fiber surface was characterized by SEM. The XPS results showed that the grafted carbon fiber has a higher N/C ratio from 0.030 to 0.061 on its surface. The grafting degree was above 2.1%. Grafting of nylon 6 improved the interface interaction between carbon fiber and nylon 6 matrix and increased the ILSS of CF/PA6 composites by 14%.
