Improvement of fatigue life of CFRP by addition of cellulose nanofiber

Technical Classification:: [ Raw Materials ] [ Product Design ]
Products:: [ Equipment / Facilities ]
Keyword:: [ Cellulose nanofiber ] [ improvement of fatigue endurance ]

Point of the Proposed Technology

By addition of the cellulose nanofiber manufactured by our company to CFRP, the bending and tension fatigue life of the CFRP is substantially increased.

Effect(s)

Over 10-times increase by addition of 0.3 wt% of the cellulose nanofiber

New Technology

・Cellulose nanofiber FMa: short fiber, IMa: long fiber
・Resin: Thermosetting epoxy resin
