Thermal analysis of composites prepared for different purposes

In recent years, rapidly developing science and technology has led to increase in research and use of composites prepared for polymer and different purposes. Polymer-based composite materials are widely used in different industries such as automotive, construction, electronics, furniture, medical and packaging. As a necessity of our age and a part of rapidly developing production chain, it is of great importance to supply the appropriate material in the applications where high thermal performance is desired. As a necessity of our age and a ring of rapidly developing production chain, it has great importance to supply the appropriate material in the applications where high thermal performance is desired. More efficient heat transfer materials are needed in order to meet the increasing need. In the light of these developments, the studies in terms of improving energy efficiency and heat transfer of materials are accelerated. For this reason, it is aimed to obtain more effective heat transfer by working on such materials and to achieve data on optimum energy efficiency. In recent years, polymer or polymer based composite materials, which are one of the subjects of interest, are thought to be used as more active materials in the sector in order to improve thermal efficiency as they have higher thermal conductivity and more appropriate physical properties compared to other materials. In this study, %20-30-40-50-60 Polypropylene (PP), %20-30 Low Density Polyethylene (LDPE) and %20-30 High Density Polyethylene (HDPE) composite were produced. Heat conduction coefficients were determined by the steady - state process of all composites produced and the results were compared with the series, parallel, geometric mean, Russel and Maxwell methods in the literature. As a result of experimental analysis, the physical properties of composites were determined and thermal analyzes of composites were made in Ansys R19 program. Finally, the results of experimental and numerical analysis were compared with each other and the application areas were proposed for the composites. It has been observed that the heat conduction coefficient of the pure polypropylene material, which is 0.12 W/mK, was gradually decreased to 0.054 W/mK in the polypropylene composite with a reinforcement phase of 60% between the test samples. Reinforcement process was applied in LDPE and HDPE materials and heat conduction coefficients of composites were also determined. According to the data obtained from the experimental results, it was observed that the analyzes carried out in the Ansys program were consistent with the results. It is thought that these studies in the thesis stage will benefit to the science, the practice and the society in order to determine the thermal characteristics of the materials.
