The purpose of this study was to investigate yield rate of carbon fibers reinforced epoxy composites in near-critical water. A CFRP (carbon fiber reinforced plastic) laminate stacked with twenty layers was used and the specimens were cut in 10 × 50 mm (thickness: 4 mm) size. The CFRP sample was placed and heated within the non-stirred bath autoclave with an electric furnace. The yield percentage is calculated by the weight percentage of eliminated resin. To check the surface of carbon fiber, scanning electron microscopy was employed. The results showed that the removal percentages of weight were between 53.9% and 97.1%. The best yield was significantly increased up to 97.1% when operating in 573 K (14 MPa) condition. This research suggests an basic data to design a commercial scale recycling system or a new low cost recycling system for CFRP waste.
