CFRP recycling technology using supercritical fluid
- Technical Classification:
- [ Recycling ]
- Products:
- Keyword:
- [ recycling ] [ subcritical fluid ] [ Supercritical fluid ]
Point of the Proposed Technology
- Compared to pyrolysis, carbon fibers can be recovered with little deterioration of the strength.
- Deposits of resin will not remain, and if carbon fibers are fabric, they can be recovered in a fabric state.
- Deposits of resin will not remain, and if carbon fibers are fabric, they can be recovered in a fabric state.
Effect(s)
Single fiber tensile strength of recovered carbon fiber → Reduction of about 10% or less compared to new fiber
CFRP using recovered carbon fiber sheet → Strength equivalent to new CFRP
CFRP using recovered carbon fiber sheet → Strength equivalent to new CFRP
