Development and experimental verification of a structural health monitoring system for composite beams with embedded fibre bragg grating sensors
Değerliyurt, Boray; Şahin, Melin; Department of Aerospace Engineering (2017)
Structural Health Monitoring (SHM) is a discipline of development and application of monitoring and detecting adverse changes and damage in a structure in operation. This study explains development of a SHM system of composite beams with embedded Fibre Bragg Grating (FBG) sensors and its verification through experiments. There are considerations that require attention during manufacturing of composite specimens with embedded sensors. During manufacturing, protective teflon tubes are added to the ingress and...
Development and production of ductile TiZrNbHfTa refractory high entropy alloy system for extreme environments
İroç, Lütfi Koray; Aydoğan Güngör, Eda; Kalay, Yunus Eren; Department of Metallurgical and Materials Engineering (2022-1-13)
High entropy alloy (HEA) is a trending material class that was discovered in the early 2000s. By definition, it consists of a single or dual phase by combining 5-13 elements with a 5-35% atomic ratio. They exhibit extraordinary properties, such as structural, mechanical, corrosive and thermal. Moreover, this field gives an opportunity to combine infinite number of elements with infinite compositions. These properties and opportunities make them candidates for various extreme application areas, which will gr...
Development and characterization of high power density cathode materials for lithium-ion batteries
Doğu, Şafak; Aydınol, Mehmet Kadri; Evis, Zafer; Department of Micro and Nanotechnology (2015)
In this thesis, facile and cost efficient aqua based synthesis method is developed to synthesize power dense and fast rechargeable LiFePO4 cathode materials. In order to obtain nano sized crystal morphology, nucleation controlled techniques were studied on precursor synthesis. These techniques are freeze (cryogenic) drying with co-precipitation and ultrasound assisted sub-sequential precipitation with vacuum drying at low temperatures (<350 K). In co-precipitation with freeze drying synthesis, star-like pla...
Development and characterization of high energy cathode materials for lithium-ion batteries
Büyükburç, Atıl; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2013)
The aim of this thesis is to produce high energy cathode materials based on LiCoO2 materials with the general formula LiCo1-xMxO2 and LiCo1-y-xMxNyO2. In order to achieve this formula, less exploited doping elements such as Mo, Cr and W will be used as well as Mn. During the study, the parameters of the processes which are solution preparation, freeze drying and calcination are optimized. According to the results, 24 hours of freeze drying is enough for drying the samples. Calcination at lower (< 700°C) tem...
Development and characterization of layered Li(NixMnyCo1-x-y)O-2 cathode materials for lithium ion batteries
Piskin, Berke; Aydınol, Mehmet Kadri (Elsevier BV, 2016-06-22)
The structure of the layered Li(NixMnyCo1-x-y)O-2 in different amounts of x and y ranging between 0.2 and 0.6, have been synthesized and investigated by powder X-ray diffraction and electron microscopy techniques. In the current work spray pyrolysis was used to obtain spherical fine-sized morphology followed by heat treatment to obtain better electrochemical activity. The precursor powders were prepared using aqueous solution via spray pyrolysis. Synthesized samples were then heat treated at 850 degrees C. ...
