Conductive and flexible carbon fiber (CF) reinforced polydimethylsiloxane (PDMS)/polypyrrole (PPy) composites were synthesized electrochemically. Electrochemical synthesis was performed at + 1.1 V using p-toluenesulfonic acid as supporting electrolyte and water as solvent. Composites were characterized by thermal gravimetric analysis, scanning electron microscopy (SEM), conductivity measurements and mechanical tests. Conductivities of composites were observed in the range of 2.2-4 S/cm. SEM studies show that CFs were coated by PDMS/PPy matrix uniformly. In mechanical tests, it has been observed that tensile strength of composites increased with increasing CF content. Higher percent elongation was achieved by the addition of PDMS. Highly flexible, foldable and mechanically strong conductive composites were obtained.

MECHANICAL PROPERTIES OF REPAIRED CARBON FIBER REINFORCED POLYMER COMPOSITES
Sonat, Emine Evren; Özerinç, Sezer; Department of Mechanical Engineering (2021-12-10)
Carbon fiber reinforced polymer (CFRP) composites are increasingly used in the aerospace industry due to their high specific strength compared to conventional metallic materials. However, a significant shortcoming of these composites is their increased susceptibility to damage. Structural repair is a common method to restore the load-carrying capacity of a damaged part when the damage size exceeds the pre-defined tolerances. Scarf and stepped bonded repair methods are the primary choice for cases that requi...
Vibration damping behavior of epoxy matrix composites reinforced with carbon fibers and carbon nanotubes
Avil, Esma; Kaynak, Cevdet; Department of Metallurgical and Materials Engineering (2019)
The main objective of this study was to investigate contribution of the nonfunctionalized multi-walled carbon nanotubes (CNT) on the vibration damping behavior of first neat epoxy resin and then unidirectional and bidirectional continuous carbon fiber (CF) reinforced epoxy matrix composites. Epoxy/CNT nano-composites were produced by ultrasonic solution mixing method, while the continuous CF reinforced composite laminates were obtained via resin-infusion technique. Vibration analysis data of the specimens w...
Flexible supercapacitor electrodes with vertically aligned carbon nanotubes grown on aluminum foils
Dogru, Itir Bakis; Durukan, Mete Batuhan; Turel, Onur; Ünalan, Hüsnü Emrah (2016-06-01)
In this work, vertically aligned carbon nanotubes (VACNTs) grown on aluminum foils were used as flexible supercapacitor electrodes. Aluminum foils were used as readily available, cheap and conductive substrates, and VACNTs were grown directly on these foils through chemical vapor deposition (CVD) method. Solution based ultrasonic spray pyrolysis (USP) method was used for the deposition of the CNT catalyst. Direct growth of VACNTs on aluminum foils ruled out both the internal resistance of the supercapacitor...
Mechanical, electrical, and melt flow properties of polyurethane elastomer/surface-modified carbon nanotube composites
Tayfun, Umit; KANBUR, YASİN; ABACI, UFUK; Guney, Hasan Yuksel; Bayramlı, Erdal (2017-06-01)
Carbon nanotube-reinforced polyurethane elastomer composites were prepared by melt-mixing. Nitric acid oxidation and silanization were applied to carbon nanotube surfaces to achieve better interfacial interactions with polyurethane elastomer. Tensile and hardness tests, differential scanning calorimetry, melt flow index test, dielectric measurements, and morphological studies of composites were reported. The best results were obtained for surface-modified carbon nanotubes containing composites with lower lo...
Electrical, mechanical and thermal properties of aligned silver nanowire/polylactide nanocomposite films
Doğanay, Doğa; Kaynak, Cevdet; Ünalan, Hüsnü Emrah (2016-08-15)
In this work, electrically conductive silver nanowire (Ag NW) filled polylactide (PLA) nanocomposites were fabricated and characterized. Ag NWs/PLA nanocomposite films were fabricated using simple solution mixing method and casted onto glass substrates via doctor blading. Following the obtainment of free standing nanocomposites through peeling off, electrical conductivity of the fabricated nano composites, interfacial interactions between Ag NWs and PLA as well as nanocomposite morphology, degree of alignme...
