Öğe Investigation of mechanical properties of composites obtained from textile wastes(Batman Üniversitesi, 2022-07-02) Adin, Mehmet ŞükrüThe textile industry is one of the manufacturing sectors that pollutes the world the most. Since textile wastes are destroyed by burning traditionally, they cause great damage to the environment. Therefore, recycling of these wastes is of great importance. One of these recycling methods is their use in the production of composite materials, the application areas of which have increased in recent years. In this study, the mechanical properties of composite materials produced using cotton and polyester fabrics from waste textiles were investigated. It has been observed that 22% of the composite materials produced with reinforcement elements at different angles (0°, 45°, 90°) are reinforcement elements and 78% are resins. As a result of the tensile tests, the highest tensile strength value was obtained with the polyester fabric with 0° reinforcement angle as 55.72 MPa. It has been found that the increase in the reinforcement angles positively affects the tensile strength in cotton fabric reinforced composites, whereas this situation occurs in the opposite way in polyester fabric reinforced composites. When the highest tensile strength values of polyester fabric and cotton fabric reinforced composite samples were compared, it was seen that the sample using polyester fabric (55.72 MPa) had 69% higher tensile strength than the sample using cotton fabric (33.05 MPa). In addition, the elongation values of polyester fabric reinforced composites were higher than cotton fabric reinforced composites.Öğe Numerical investigation of fatigue behaviors of non-patched and patched aluminum pipes(Hibetullah KILIÇ, 2021-06-01) Adin, Hamit; Yıldız, Bilal; Adin, Mehmet ŞükrüIn this study, the fatigue behaviors of non-patched and patched aluminum pipes were investigated numerically. The Finite Element Method was used for fatigue analysis in the study. Finite Element Method was implemented with Ansys Workbench (15.0) program. Al 6063 type aluminum pipe, DP-460 type adhesive and [0/90]2 reinforced angled glass-epoxy composite patch material were used in the analyzes. As a result of the numerical study, it was observed that patch size is an effective parameter in fatigue strength and that quarter-circle and semi-circular composite patches increase the fatigue life. It was also observed in the analyzes that the quarter-circle patched aluminum pipes achieved higher fatigue strength.Öğe Numerical investigation of fatigue behavior of non-patched and patched aluminum/composite plates(Ahmet ÇALIK, 2021-12-20) Adin, Hamit; Sağlam, Zeyni; Adin, Mehmet ŞükrüIn this study, the fatigue behavior of composite patched and non-patched Al 5083 aluminum plates was numerically investigated. Al 5083 Aluminum plates with semi-circular notched (2, 3 and 4 mm long cracked) and "V" notched (30°, 45° and 60° angled) were used in the analyzes. Mechanical properties of Al 5083 Aluminum plate, DP460 type adhesive of produced by 3M and [0°]8 glass fiber reinforced composite patch material was used for the study. The Finite Element Method was applied for numerical study. Numerical analyzes were performed with the Ansys version 15.0 Workbench Package program. As a result of the numerical study, the highest fatigue life (1593.2 N) is seen on the 30° angled "V" notched and patched specimen. However, the fatigue life in non-patched specimen (30° angled "V" notched) was found to be 277.69 N. Thus, the study revealed that the composite patch's contribution is very important.Öğe Partikül takviyeli yapıştırıcılarla üretilmiş jute kompozit malzemelerin mekanik özelliklerinin deneysel olarak belirlenmesi(Batman Üniversitesi, 2018-05) Adin, Mehmet Şükrü; Ergün, Raşit Koray; Adin, HamitBu çalışmada jute tipi kumaşlardan üretilmiş kompozit malzemelerin mekanik özellikleri incelenmiştir. Kompozit malzemeler, yapıştırıcı malzemesi kullanılarak 11 katman olacak şekilde üretilmiş olup verilen ölçü ve değerlere göre kesilmiştir. Elde edilen numuneler çekme deneyine tabi tutulmuştur. Verilere göre alüminyum tozun kompozit numunede daha sağlam bir yapı oluşturduğu gözlemlenmiştir. Deneysel olarak elde edilen sonuçlar tablo ve grafik olarak sunulmuştur. Sonuç olarak; partikül katkılı yapıştırıcı kullanılmasıyla elde edilen kompozit malzemelerin çekme hasar yükünün arttığı görülmüştür.Öğe Optimization of mechanical properties of composites obtained from textile wastes using Taguchi and ANOVA methods(Batman Üniversitesi, 2022-07-02) Adin, Mehmet ŞükrüToday, one of the most polluting manufacturing sectors is the textile industry. Therefore, recycling of these wastes is of great interest. One of the solutions applied for the recycling of these wastes is their use in the manufacture of composites. In this study, optimization of manufacturing parameters was made in order to obtain plates with the highest tensile strength from composite materials to be produced from textile wastes by using Taguchi and ANOVA methods. As a result of the study, it was found that the tensile strength of the composite plates made of polyester fabric was higher than the plates made of cotton fabric, and the signal/noise (S/N) ratios of 0° angle reinforced composites were lower than 90° angle reinforced composites. It was observed that there was a nearly linear increase in the S/N ratios depending on the increase in the number of reinforcements. As a result of the ANOVA analysis, it was found that the most effective factor according to the tensile strength was the reinforcement angle with 45.06%. It was observed that the highest tensile strength of the composite plates obtained from cotton fabric was 40.058 MPa with 90° angled reinforcement elements and 14 reinforcements, and the lowest tensile strength was 23.451 MPa with 0° angled reinforcement elements and 10 reinforcements. In composite plates obtained from polyester fabric, the highest tensile strength was 42.136 MPa with 45° angled reinforcement elements and 14 reinforcements, and the lowest tensile strength was 27.112 MPa with 0° angled reinforcement elements and 10 reinforcement numbers. It has been found that the tensile strength of the composite plates obtained from polyester fabric is higher than that of the composite plates obtained from cotton fabric.
