Abstract Scope Particulate ceramic-polymer composites are widely used in electronic devices, biomedical engineering and other applications. This work presents the results of an experimental study of the fracture behaviors of epoxy-alumina, a typical ceramic-polymer composite. Single-edge notched bend (SENB) specimens with 0, 5, 10, …, 25 vol% filler fractions were fabricated, respectively. Three-point bending test was performed using mechanical tester coupled with micro X-ray computed tomography (micro-CT). The crack paths were revealed in the micro-CT images and the toughening mechanisms were discussed. 3D-full field strain field was computed through digital volume correlation (DVC). Fracture mechanics theories were applied to analyze the crack length and obtain the crack resistance curves. Results show that matrix-particle interfaces were the weakest link, where cracks often initiated from. Furthermore, saline-coated alumina-epoxy specimens were fabricated, tested, and shown to improve the fracture toughness. This method can potentially be extended to study the fracture behaviors of other particulate composites.
