The purpose of the study is to reduce the damage of the soldier boots, which subject the blast load. The boot sole was reinforced to perform the study. Thermoplastic polyurethane (TPU) and multi-walled carbon nanotube (MWCNT) materials were used for this reinforcement. In addition, TPU 508 material was used as energy absorber, and Carbon-Kevlar fiber composite was utilized to decrease the impact effect of blast load. Acceleration test system was used to simulate the blast load. Three different boots were used in the study (ordinary boot, semi-damped boot, and fully damped boot). Twin-screw extruder was used to blend melted material to prepare polyurethane MWCNT with weight fraction from 1% to 5%. In addition, mechanical properties of these materials were obtained by tensile tests. The best mechanical properties were obtained with the weight fraction of 1% MWCNT. Acceleration test was applied to measure the energy damping performance of new designed boot sole. As a result of the study, the best reduction on the blast load was obtained nearly 12% with the fully damped soldier boot.

In this study, a new algorithm has been developed for Design Optimization of composite plates using Tsai-Wu criteria. Von-Mises stress criteria is used as design variable for the stress based Design Optimization problems. It is used to understand the effect of combined stresses on the isotropic materials. However, Von-Mises stress analysis is not appropriate for anisotropic composite materials. To define the strength of composite materials, maximum stress, maximum strain, Azzi Tasi Hill and Tsai-Wu criterias are used. In this study, failure index was used as design criteria and Tsai-Wu criteria was used to calculate this value in the optimization algorithm. Topology optimization, which is used for mass and shape optimization on structures, is a design tool. In this study, a new algorithm has been developed for topology optimization of composite materials. By using this algorithm, common geometric models and different fiber angles have been investigated. Nearly 50% mass reduction have been obtained by using the developed algorithm.

Mechanical behaviors of materials are determined by experimental tests. In cases where the tests cannot be performed or a small number of samples can be tested, performing the numerical analysis is widely used for quick and reliable designs. This is particularly important for composite materials that are costly to design and manufacture but are widely used in many industries. Drop weight impact is a widely used test method to investigate the behavior of materials under the impact loads. Particularly in the areas where thin structures are frequently used, the behavior of materials under impact load is important. In this study, the behaviors of Carbon/Epoxy and Glass/Epoxy composite plates under the drop weight impact load was simulated. Composite materials have been used to have symmetrical fiber orientations. The effects of different configurations of Carbon/Epoxy and Glass/Epoxy composite plates are considered. Also, the thickness of the plate was increased by increasing the number of layers of the composite material and the effect of thickness increase on impact load was investigated. As a result, it is seen that the Carbon/Epoxy composite plate has a higher impact resistance than the Glass/Epoxy composite plate. The deformation of the Glass/Epoxy composite plate is higher than the Carbon/Epoxy composite plate. The maximum impact force increases with thickness increase for both materials.
