Fig. 8

(a)–(c). Optical micrographs (× 20 magnification) of leather-epoxy composites post mechanical loading, highlighting surface scratches and localized resin deformation. The absence of clearly resolvable failure mechanisms at this scale indicates the limitation of optical microscopy in capturing micro-scale damage features, warranting the use of higher-resolution techniques for detailed failure analysis.
