Research Abstract

I investigated a reuse method of waste GFRP as an interleaf material of unidirectional GFRP laminates. Waste GFRP milled chips were used for the interleaf of composite laminates with vacuum assisted resin transfer molding. The interleaf causes the shear support and fiber bridging effect in static tests. Fatigue crack arrest by the interleaf was found in the mode II delamination fatigue test.
