Çalışma kompozit malzemelerin üretilmesi ve üretilen malzemelerin mekanik, morfolojik ve fonksiyonel özelliklerinin belirlenmesi olmak üzere iki aşamadan oluşmuştur. Mekanik özelliklerin belirlenmesi için çekme ve burkulma deneyleri gerçekleştirilmiştir ve elde edilen sonuçlar karşılaştırılmıştır. Belirlenen en uygun katkı oranlı numunelere ve katkısız numuneye fonksiyonel yapısını belirlemek için FT-IR ve morfolojik yapısını belirlemek için SEM analizleri gerçekleştirilmiştir. Çekme deneyleri sonucunda çekme yükü, çekme gerilmesi ve elastisite modülü verileri incelendiğinde kompozit numune için %0,5 KNT oranının en uygun olduğu görülmüştür....

Research paper thumbnail of Characterization of E-glass/epoxy Modified with Recycled Rubber Particles and Multi-walled Carbon Nanotubes

The chemical degradation method was the novel method. This novel method that has been discovered was more advantageous than other methods (pyrolysis and devulcanization). The mechanical and characteristic properties of the composite materials were determined using rCBM and MWCNT additives of 0.1 to 2.0%. The study consisted of two phases, being the production of the composite materials and the determination of mechanical, morphological and functional properties of the materials produced. As a result, both the additives increased the strength of the composite material. It was demonstrated via SEM and FT-IR analyses that carbon-based additives obtained by degradation of waste tires failed to bond to epoxy resin in the production of the composite material.

Studies on electric vehicles have become very popular today. In the automotive sector, sectoral dynamics and needs are rapidly changing; restrictions and demands are bound by strict rules and high value-added innovative studies are applied intensively. Supporting this area with academic data will contribute to research and development activities in this field. In this study, analysis and production studies were performed on a 3-wheeled vehicle chassis driven by electric energy. The chassis structure was designed and analyzed with details. The chassis aimed to be produced as a result of the study was analyzed in detail according to brake, modal and cornering analysis. As a result of these analyses, it was found that this chassis has a reliable structure according to the specified driving dynamics parameters. By adopting new requirements, technologies and analysis outputs for the system, a modular platform structure that can be used for various applications were created. The design and production processes of an innovative and applicable chassis structure for the electric vehicle ecosystem are given in detail.

The optimum material combination was determined by examining with multi-criteria decision making methods, taking into account the analyzes made and different criteria. Figure A. Required steps to determine the chassis material Purpose: The main purpose of this study is to determine the type/combinations of chassis materials that enable the chasis, the structure that carries many systems of the car, to be safe, durable, cost-effective, easy to manufacture, and to have the appropriate chemical composition and physical properties in order to realize the most efficient and effective applications of the movable or fixed connections on it. Theory and Method: The study focused on the choice of chassis material for the chassis design of a 3wheeled L2E class electric. Safety, cost, weldability and machinability factors for St52, Ck45 and C4140 steels were comparatively analyzed using the Technique for Order Preference By Similarity (TOPSIS) and VIKOR, multi-criteria decision making methods (MCDM). As a result of the analyses, with which specified factors and materials the horizontal elements, vertical elements and ribs that make up the chassis will be the most suitable and efficient has been determined. Results: With the analysis results obtained in the software environment; the construction of the chassis horizontal profiles from C4140 tempered steel and the other chassis elements from St52 general structural steel turned out to be the most ideal option with both multi-criteria decision making methods. As the second ideal optimization option, it was concluded from the analyses that while the horizontal profiles and ribs could be made of C4140 tempered steel, all vertical profiles could be made of St52 general structural steel. Conclusion: In this study, analyzes were carried out in software environment on a 3-wheeled L2E class electric vehicle chassis structure and solutions were presented accordingly. In this context, this study will shed light on future studies. It will contribute to the creation of a wide and increasingly deep literature on this subject both with the new studies planned after this study and the studies that different researchers will carry out with different vehicle types and innovative materials. Moreover, an information infrastructure supported by scientific studies will be provided to chassis manufacturers and vehicle producing companies.
