N2 - In this study, we investigated the mode II delamination fatigue crack growth characteristics of GFRP laminates with a waste GFRP milled chip interleaf for recycling waste GFRP. We used a recycle method investigated in a previous study. End-notched flexure fatigue tests were conducted with GFRP laminates with the interleaf and UD laminates under four types of maximum test loads with Pmax = 0.69, 0.59, 0.49, and 0.44 kN. In addition, we observed fatigue damage during tests and fracture surfaces. We found that the fatigue characteristics could be divided into three regions according to the load levels. In the case of Pmax = 0.44 kN, the crack in the GFRP laminates with the interleaf did not propagate, whereas the crack in the normal UD laminates grew to failure under the same test load. This result indicated that the interleaf was effective in impeding mode II delamination fatigue crack growth.
