Recycling 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.

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

Conventional Technology

New Technology
