The properties of 30 wt% short glass fiber (SGF) reinforced acrylonitrile-butadiene-styrene (ABS) terpolymer and polyamide 6 (PA6) blends prepared with extrusion were studied using the interfacial adhesion approach. Work of adhesion and interlaminar shear strength values were calculated respectively from experimentally determined interfacial tensions and short beam flexural tests. The adhesion capacities of glass fibers with different surface treatments of organosilanes were evaluated. Among the different silanes tested, gamma-aminopropyltrimethoxysilane (APS) was found to be the best coupling agent for the glass fibers, possibly, because of its chemical compatibility with PA6. Tensile test results indicated that increasing amount of PA6 in the polymer matrix improved the strength and stiffness of the composites due to a strong acid-base interaction at the interface. Incorporation of PA6 to the SGF reinforced ABS reduced the melt viscosity, broadened the fiber length distributions and increased the toughness of the composites. Fractographic analysis showed that the incorporation of PA6 enhanced the interactions between glass fibers and the polymeric matrix.

Effects of glass fiber reinforcement and thermoplastic elastomer blending on the mechanical performance of polylactide Varsavas, S. Deniz; Kaynak, Cevdet (2018-06-01) The purpose of this study was to investigate how optimum mechanical properties (strength-modulus-toughness) of inherently very brittle polylactide (PLA) could be obtained by reinforcing with E-glass fibers (GF) and blending with thermoplastic polyurethane elastomer (TPU). Composites and blends were compounded by twin-screw extruder melt mixing, while specimens were shaped by injection molding. SEM analyses revealed that 15 wt% GF and 10 wt% TPU domains, alone and together, could be uniformly distributed in ...
Effects of glass fiber content, 3D-printing and weathering on the performance of polylactide Varsavaş, Sakine Deniz; Kaynak, Cevdet; Department of Metallurgical and Materials Engineering (2017) The purpose of the first part of this thesis was to investigate how optimum mechanical properties (strength-modulus-toughness) of inherently very brittle polylactide (PLA) could be obtained by reinforcing with E-glass fibers (GF) and blending with thermoplastic polyurethane elastomer (TPU). Composites and blends were compounded by twin-screw extruder melt mixing, while specimens were shaped by injection molding.

Effects of microcompounding process parameters on the properties of ABS/polyamide-6 blends based nanocomposites Oezkoc, Gueralp; Bayram, Göknur; Quaedflieg, Martin (Wiley, 2008-03-05) Melt intercalation method was applied to produce acrylonitrile-butadiene-styrene/polyamide-6 (ABS/ PA6) blends based organoclay nanocomposites using a conical twin-screw microcompounder. The blend was compatibilized using a maleated olefinic copolymer. The effects of microcompounding conditions such as screw speed, screw rotation-mode (co- or counter-), and material parameters such as blend composition and clay loading level on the morphology of the blends, dispersibility of nanoparticles, and mechanical pr...
Effects of RTM mold temperature and vacuum on the mechanical properties of epoxy/glass fiber composite plates Kaynak, Cevdet; Isitman, Nihat Ali (2008-08-01) The purpose of this study is to investigate the effects of mold temperature, application of vacuum at resin exit ports, and initial resin temperature on the mechanical properties of epoxy matrix woven glass fiber reinforced composite specimens produced by resin transfer molding (RTM). For this purpose, six mold temperatures (25, 40, 60, 80, 100, and 120 degrees C), two initial resin temperatures (15 and 28 degrees C), and vacuum (0.03 bar) and without vacuum (similar to 1 bar) conditions are utilized. Speci...
Effects of electrospinning process parameters on nanofibers obtained from Nylon 6 and poly (ethylene-n-butyl acrylate-maleic anhydride) elastomer blends using Johnson S-B statistical distribution function Biber, Erkan; Gündüz, Güngör; MAVİŞ, BORA; Colak, Uner (2010-05-01) The impact strength of Nylon 6 can be further improved by blending it with ethylene-butyl acrylate-maleic anhydride elastomer. The blending is achieved in solution phase. Due to incompatibility of Nylon 6 and the elastomer, a special mixture of solvents is used to dissolve both components. The solution is electrospun, and the effects of the process parameters on the expected radii of nanofibers are investigated. The effects of process parameters such as polymer concentration in solution, electrical field, d...
