In this study, a method of manufacturing high-density polyethylene (HDPE)-based carbon fibers was studied using a hybrid crosslinking method. The HDPE precursor fibers were primary crosslinked with an electron beam (E-beam) at an irradiation dose of 1000-2500 kGy, and secondary crosslinked in sulfuric acid at 80-110°C for 60 minutes. Hybrid crosslinked fibers were carbonized for 5 minutes at a temperature of 900 °C. Tensile properties of the primary and secondary crosslinked fibers were analyzed by UTM, thermal properties were analyzed by DSC and TGA, and morphology was analyzed by XRD. The morphology of the resulting carbon fiber was analyzed by SEM and XRD. As a result, HDPE-based carbon fibers having (002) and (10l) peaks, which are the intrinsic XRD peaks of carbon fibers, were successfully prepared. |
