Environmentally friendly, highly efficient Epoxy-based Carbon Fiber Reinforced Plastic Green Recycling system using Supercritical water |
| 초록 |
The carbon fiber reinforced plastics (CFRPs) waste has occurred by increasing use of CFRPs. Thus, the concern of environmental problem and high cost is proposed importance of recycling CFRPs. So, we applied CFRPs recycling system using supercritical water with high reactivity, low viscosity, and dielectric constant, respectively. Also, the recycled CFs (R-CFs) was applied to a cyclic butylene terephthalate (CBT) to prepare a conductive polymer composite. In this study, we carried out decomposition of epoxy from CFRPs in the supercritical fluid by water (at 410℃, under 280bar is SCF conditions). We observed the successful epoxy decomposition from recycling carbon fiber through FT-IR, thermogravimetric analysis (TGA), Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). After epoxy removal, morphology of the R-CFs showed undamaged surface and the tensile strength of R-CFs has similar value with the neat CFs via Favimat equipment. |
