The effects of carbon fiber amount and length were studied on the flame retardant, thermal, and mechanical properties of the intumescent polypropylene composites. The flame retardant properties of the intumescent polypropylene-based composites were investigated using limiting oxygen index, vertical burning test (UL-94), and mass loss calorimeter. The mechanical properties of the composites were studied using tensile test and dynamic mechanical analysis. According to the flammability tests results, the antagonistic interaction was observed between carbon fiber and ammonium polyphosphate. The limiting oxygen index value reduced steadily as the added amount of carbon fiber increased. Mechanical test results revealed that the addition of carbon fiber increased the tensile strength and the elastic modulus as the added amount increased. No effect of carbon fiber length was observed on the flammability, fire performance, and tensile properties of composites, whereas the elastic modulus increased as the carbon fiber initial length increased.

Effects of processing parameters on mechanical and thermal properties of glass mat reinforced nylon 6 composites Akkaoui, W; Bayram, Göknur (SAGE Publications, 2004-01-01) Nylon 6 (PA6)/Glass Mat (GM) composites and pure PA6 were prepared by compression molding technique and the effects of molding temperature, pressure application time and GM content on the final properties of the materials were investigated. At each temperature and pressure application time, the composite with one layer GM had higher tensile strength, tensile modulus but lower % elongation at break than neat PA6. Processing parameters did not significantly influence the tensile behavior of the pure PA6 and P...
Contribution of carbon nanotubes to vibration damping behavior of epoxy and its carbon fiber composites Avil, Esma; Kadioglu, Ferhat; Kaynak, Cevdet (SAGE Publications, 2020-04-01) The main objective of this study was to investigate contribution of the non-functionalized multi-walled carbon nanotubes on the vibration damping behavior of first neat epoxy resin and then unidirectional and bidirectional continuous carbon fiber reinforced epoxy matrix composites. Epoxy/carbon nanotubes nanocomposites were produced by ultrasonic solution mixing method, while the continuous carbon fiber reinforced composite laminates were obtained via resin-infusion technique. Vibration analysis data of the...
Effect of spraying rate on microstructure of spray deposited Al-Fe-V-Si alloy Kalkanlı, Ali (Informa UK Limited, 2003-12-01) In this study gas atomisation and spray deposition of a series of AlFeVSi alloys were carried out. Traces of transient liquid were observed as lamellar structure in the middle of the specimen. The heat transfer conditions of this structure were modelled by finite difference calculation. Metallographic specimens for optical microscopy were prepared from the preforms formed in these processes. Optical microscopy showed the presence of dispersoids in the specimens. The dispersoids were characterised as AlFeVSi...
Effect of stress ratio on the rate of growth of fatigue cracks in 1100 Al-alloy Bilir, Ömer.G.; Harun, Metin (Elsevier BV, 1990-1) Axial load fatigue crack propagation tests were conducted on notched sheet specimens made of 1100 aluminum alloy. These tests were made at stress ratios (ratio of the minimum stress to the maximum stress) ranging from −0.5 to 0.5 in order to study the effects of stress ratio on fatigue crack growth. Experimental fatigue crack propagation data were analysed using Paris-Erdoǧan stress intensity analysis. The data from the tests at different stress ratios showed that two regions, namely, region I and region I...
Influence of Zinc Oxide on Thermoplastic Elastomer-Based Composites: Synthesis, Processing, Structural, and Thermal Characterization ÇELEBİ, HANDE; Bayram, Göknur; DOĞAN, AYDIN (Wiley, 2016-08-01) It was aimed to investigate how thermal conductivity and stability properties of synthesized thermoplastic elastomers were influenced by zinc oxide (ZnO) additives which differed in size and surface treatment. ZnO particles were prepared by the homogeneous precipitation method by mixing aqueous solutions of hexamethylenetetramine (HMT) and zinc nitrate. The obtained particles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Poly(v...
