Schematic representation of the experimental design process used in the study.

Notes: The experiment had four major steps: 1) preparation of polycaprolactone (PCL) solution, 2) deposition of unidirectional PCL fibers on a titanium plate, 3) fabrication of Ti–poly(methyl methacrylate) (PMMA) specimens with and without PCL fibers using a custom-made mold that can be found in Khandaker et al¹ and 4) conducting fracture tests on the sandwiched Ti–PMMA specimens under tension-, mixed-, and shear-load conditions. a Is the initial crack length, B is the length, W is the width and h shows the thickness of a sample.
