Chemical Recycling of CFRP at Ambient Pressure using Water with Surfactant |
| 초록 |
In general, the cross-linked epoxy resin is a thermosetting resin, which cannot be dissolved in an organic solvent. Therefore, epoxy resin applications, especially carbon fiber reinforced plastic, have been known to be difficult to recycle. In our study, we succeeded in dissolving the epoxy resin within 2 h at atmospheric pressure and a reaction temperature of 100 C are optimal conditions for the depolymerization; used benzyltrimethylammonium bromide (BTAB) and sodium dodecyl sulfate (SDS) for the interfacial separation between the epoxy resin and carbon fibers (CFs). The surfactant system maximized recycling efficiency in both pretreatment and the main reaction of the CFRP recycling process. These results indicate that our developed method is suitable for the efficient reclamation of high-quality carbon fibres from CFRP scrap. |
