Recovery of carbon fibers from CFRP and surface modification of the fibers using superheated steam
- Technical Classification:
- [ Recycling ]
- Products:
- Keyword:
- [ fiber surface modification ] [ recycle ] [ superheated steam ]
Point of the Proposed Technology
・Matrix resin of CFRP is decomposed and vaporized by superheated steam treatment, and various lengths and states of carbon fibers can be recovered.
・Superheated steam treatment with process gases (N2, etc) enables the surface modification of fibers (improvement in adhesion between fiber and resin, increase in fiber strength).
・Superheated steam treatment with process gases (N2, etc) enables the surface modification of fibers (improvement in adhesion between fiber and resin, increase in fiber strength).
Effect(s)
Lowering of CFRP reproduction costs
Conventional Technology
New Technology
・ Various lengths and states of carbon fiber can be recovered by SHS treatment.
・ SHS treatment with process gas (N2, etc) enables the surface modification of fibers (improvement in adhesion between fiber and resin, increase in fiber strength).
・ SHS treatment with process gas (N2, etc) enables the surface modification of fibers (improvement in adhesion between fiber and resin, increase in fiber strength).
