| Research Abstract |
An increase of interlaminar fracture toughness in CFRP laminates due to an intrinsic shape memory effect of pre-strained SMA wires was demonstrated. Mode-I interlaminar fracture toughness of CFRP stitched by SMA wire with small volume fraction of 0.09% was increased by 30%. A feasibility study on damage induced electric property change of SMA wires was conducted in order to identify damaged area of SMA stitched CFRP.
