Abstract
The purpose of this study is to improve the mechanical properties of carbon fiber reinforced thermoplastics (CFRTP) using polyamide6 (PA6) as a matrix resin. To achieve this purpose, we investigated the surface modification method for both carbon fiber fabrics (CFFs) and PA6 films. In order to improve the adhesion between CFFs and PA6 films, ozone oxidation treatment was adopted. This treatment was carried out for both CFFs and PA6 films. In comparison with the untreated sample, it was found that flexural strength and tensile strength increased 106% and 44%, respectively. This would be because the oxygen-containing functional groups were generated on both surfaces of CFFs and PA6 films by the effect of the ozone oxidation treatment, it was assumed that the adhesion of the interface was improved.
