Polyamides (PAs), which are one of the largest engineering thermoplastic materials, have found major usages in technical application sgements, such as automobile, electronics, and packaging. In this study, to attain PA-based materials with enhanced mechanical and thermal properties, electron beam (EB) irradiation and carbon fiber (CF) are adopted as a highly efficient crosslinking process and reinforcing filler, respectively. For the purpose, PA6-based composites with different CF contents were melt-compounded and hot-pressed. Subsequently, the PA6/CF composite sheets are irradiated with different EB doses of 30-200 kGy. The morphological and microstructural features of PA6/CF composites are characterized by using SEM, FT-IR, and XRD. The thermal transition, thermal stability, and mechanical properties of the composites are investigated with DSC, TGA, and DMA, respectively. |
