In this study, the reasons why the bones, which make up the skeletal system and were subjected to continuous compression, were created as a natural composite structure were investigated. They had been compared by being subjected to compression test separately together with sheep bone, wood, plastic and steel pipes prepared in the same dimensions. Thus, the advantages of being a composite material of the bone to our body were investigated by comparing with other materials; the data obtained from the experiments were evaluated and reported. Besides the results obtained from after the compression tests were supported by using the graphics and photographs.

The use of nanomaterials is gradually increasing with the progress of nanotechnology. In particular, the production of nanocomposites incorporating nanoparticles is one of the most significant areas in which nanomaterials are being used increasingly. The first objective of this research was to detect the punch shear or penetration resistance behavior and damage mechanisms of hybrid nanocomposites obtained by using silica (SiO2) nanoparticles. For that purpose, six different SiO2 hybrid nanocomposites with different laminations three layer (3La), 5La, 7La, 11La, 15La and 21La and different thicknesses (HC) of 0.95∼4.98 mm, were made by using vacuum assisted transfer molding (VARTM). During this research, quasi-static punch-shear (QS-PS) tests at span punch ratios (SPRs) of 1.16, 1.33, 1.67, 2.00, 2.33, 2.67, and more were conducted to determine quasi-static penetration mechanics and penetration resistance behavior. Moreover, deflection, energy dissipation, damage area, stiffness, and peak force values were investigated through experimental results and scanning electronic microscope (SEM) images.
