Fig. 6

Thermoplastic failure surface images (column A) and profile heat maps (column B) are shown with corresponding HTPB failure surface images (column C) and profile heat maps (column D). The red line on the images denotes the end of the initial delamination. Mode I failures are shown for PLA-U (row 1), ABS (row 2), PVDF-M (row 3), PVDF-T (row 4), PVDF-S (row 5), PVDF-B (row 6), and 10% PCL (row 7). Some HTPB layers have subsurface bubble artifacts.
