Recycling of carbon fiber reinforced polymer composites via solvolysis |
| 초록 |
Carbon fiber reinforced polymer (CFRP) composites have excellent characteristics so that they have been used for several fields such as aerospace industry and aviation materials and so on. However, waste CFRP composites are difficult to be recycled because they contain thermosetting plastics such as epoxy resin. In this study, in order to recycle waste CFRP materials, they were treated with organic solvents along with sodium hydroxide under refluxing. Carbon fibers and epoxy resins were well-separated under the experimental conditions. Scanning electron microscopy images confirmed that the curing polymer resins have been totally removed from the carbon fibers. The recovered organic materials were converted to curing agents by mixing with appropriate amounts of commercial amines. An epoxy resin was cured using the recovered curing agent. The cured epoxy resins were characterized with DSC and DMA. The experimental results will be presented in detail. |
