With increasing demands in bone repair and replacement, this research investigates the microstructure, properties and performance of bovine bone, human bone, and synthetic materials. Doing so, experimental approaches were used to exam and compare bones, as well as mimicking nature by developing a synthetic material to repair bones. Experimentally, bovine bone, tumor-free human bone, and cancerous human bone were studied via the small scale mechanical loading test. Failure analysis was conducted via optical and electronic microscopic techniques. Characterization results were used to develop a synthetic material that possesses strength and strain needed as a bone material. Characterizing techniques include a small punch test, scanning electron microscope (SEM), optical microscope and x-ray diffraction (XRD) were used for experimental approach. The results showed that small punch tests in longitudinal and tangential directions showed different mechanical properties and failure mechanisms. Cancer cells in human bone caused the bone softening and lowered the density. Synthesized epoxy-silicone-geopolymer material had higher deformability than bone. Understanding obtained in this research helps us to develop better synthetic bone materials in future. This thesis is composed of six chapters. The first chapter covers as an introduction to understand the purpose and motivation of present studies, and this section followed by the details of the motivation and objectives of this research. The third chapter explains experimental approaches that were conducted to meet the objectives. The fourth chapter describes the results and the major discovery of the experiments, and the results will be discussed in the Chapter IV. Finally, the last chapter provides the conclusions and recommendations for future work.
