Comparison of Mode I energy release rate of tested composites with literature data: (A) GI initiation, and (B) GI propagation. Legend: circles identify the laminates tested in the present work (solid black circle, reference; black circles, plain Nylon 66 mats; blue circles, mats impregnated with the 3.0 wt% NBR solution; red circles, mats impregnated with the 7.0 wt% NBR solution); yellow polyamide nanofibers26; green, NBR/PCL nanofibers32; spent fucsia, NBR/Nomex nanofibers33; dark blue, PEO nanofibers46; grey, “other” nanofiber types26.
