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 specimens were evaluated by half-power bandwidth method; and the mechanical properties of the specimens were determined with three-point bending flexural tests, including morphological analyses under scanning electron microscopy. It was generally concluded that when even only 0.1 wt% carbon nanotubes were incorporated into neat epoxy resin, they have contributed not only to the mechanical properties (flexural strength and modulus), but also to the vibration behavior (damping ratio) of the epoxy. When 0.1 or 0.5 wt% carbon nanotubes were incorporated into continuous carbon fiber reinforced epoxy matrix composites, although they have no additional contribution to the mechanical properties, their contribution in terms of damping ratio of the composites were significant.

Studies on the modification of interphase/interfaces by use of plasma in certain polymer composite systems Akovali, G; Dilsiz, N (Wiley, 1996-04-01) Calcium carbonate and carbon fiber surfaces were modified by use of a series of plasma polymers at different selected plasma conditions, and the effect of surface modification, mainly on the mechanical properties of composite systems prepared, was investigated. The matrices for the composite systems employed were polypropylene and epoxy, for the chalk and C fiber, respectively. Mechanical and thermal studies and scanning electron microscopy (SEM) pictures revealed that inclusion surfaces, being independent ...
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...
Effect of Microfiber Reinforcement on the Morphology, Electrical, and Mechanical Properties of the Polyethylene/Poly(ethylene terephthalate)/Carbon Nanotube Composites Yesil, Sertan; Koysuren, Ozcan; Bayram, Göknur (Wiley, 2010-11-01) In situ microfiber reinforced conductive polymer composites consisting of high-density polyethylene (HDPE), poly(ethylene terephthalate) (PET), and multiwalled carbon nanotube (CNT) were prepared in a twin screw extruder followed by hot stretching of PET/CNT phase in HDPE matrix. For comparison purposes, the HDPE/PET blends and HDPE/PET/CNT composites were also produced without hot stretching. Extrusion process parameters, hot-stretching speed, and CNT amount in the composites were kept constant during the ...
Effect of carbon fiber amount and length on flame retardant and mechanical properties of intumescent polypropylene composites ATABEK SAVAŞ, Lemiye; Mutlu, Aysenur; Dike, Ali Sinan; Tayfun, Umit; DOĞAN, Mehmet (SAGE Publications, 2018-02-01) 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 antag...
Production of graded porous polyamide structures and polyamide-epoxy composites via selective laser sintering Jande, Yusufu A. C.; Erdal Erdoğmuş, Merve; Dağ, Serkan (SAGE Publications, 2014-06-01) Selective laser sintering was used for producing uniformly porous and graded porous polyamide structures. The porous structures were infiltrated with epoxy to produce composites. The porous and composite specimens were physically and mechanically characterized. Within the capabilities of the selective laser sintering machine and the materials used, porosities in the range 5-29% could be obtained in a controlled, repeatable manner. The ultimate tensile strength of the produced uniformly porous polyamide stru...
