Quasi-Static Loading Test on Di-AC embedded 3-Ply CFRP
with Delamination
– Strain rate: 0.0032 mm/sec
– Epoxy Resin: Hardener (100:27)
– 5 wt% Dimeric Anthracene (Di-AC, mechanophore)
– Dimension: 55mm(L) x 20mm(W) x 0.9mm (T)
– Field of View: 22mm x 22mm
– Induced delamination using Teflon
– Notch of length ≈1mm at the left edge of the specimen
- Intensity of fluorescence increases as strain increases
- Intensity increases around induced delamination – feasibility of mechanophore for in situ damage detection
