Improvement in mechanical, electrical, and shape memory properties of the polystyrene-based carbon fiber-reinforced polymer composites containing carbon nanotubes
Erkmen, Berrak; Bayram, Göknur (2021-02-01)
Carbon fiber-reinforced polymers based on polystyrene matrix containing elastomer and carbon nanotubes (CNTs) were produced by compression molding. The effects of carbon fabric (CF) concentration and silane treatment on the morphology, mechanical, electrical, and shape memory properties of the multilayer composites were investigated. The SEM analyses showed that fibers of the silane-treated CFs were more homogeneously covered with the polymer layers than the untreated CFs. The tensile strength and modulus o...
Improvements in microstructural, mechanical, and biocompatibility properties of nano-sized hydroxyapatites doped with yttrium and fluoride
BAŞAR, Burcin; Tezcaner, Ayşen; Keskin, Dilek; Evis, Zafer (Elsevier BV, 2010-07-01)
Hydroxyapatite was doped with Y3+ (2.5, 5 and 7.5 mol%) and F (2.5 mol%) ions (2.5YFHA, 5YFHA, 7.5YFHA, respectively) to compare its structural and mechanical properties and cellular response with pure-hydroxyapatite. No second phases were observed by X-ray diffraction spectra of 2.5YFHA. Doped hydroxyapatites had F- bonds in addition to OH- bonds. Hydroxyapatites sintered at 900 and 1100 degrees C were in nano-size. 7.5YFHA sintered at 1300 degrees C had the highest microhardness value. 2.5YFHA sintered at...
Improvement in sinterability and phase stability of hydroxyapatite and partially stabilized zirconia composites
Evis, Zafer; KUTBAY, IŞIL (Elsevier BV, 2009-03-01)
Composites of hydroxyapatite with partially stabilized zirconia with MgO or MgF2 were pressureless sintered between 1000 degrees C and 1300 degrees C. The reactions and transformations of phases were verified by X-ray diffraction. For the hydroxyapatite and zirconia composites with MgO, calcium from the hydroxyapatite diffused into the zirconia phase, and the hydroxyapatite decomposed to tri-calcium phosphate at sintering temperatures higher than 1000 degrees C. Above about 1200 degrees C, CaZrO3 was formed...
Improvement of mechanical and flame retardancy properties of biocomposites based on low density polyethylene and polylactic acid
Altun, Yasemin; Bayramlı, Erdal; Doğan, Mehmet Onur; Department of Polymer Science and Technology (2015)
The main objective of this study was to improve the mechanical and flame retardant properties of low density polyethylene (LDPE) and poly (lactic acid) (PLA) based biocomposites. Wood flour (WF) and jute fabric were used as the fillers. In the mechanical property improvement studies with LDPE, the effect of two compatibilizing agents MA (random terpolymer of ethylene, acrylic ester and maleic acid) and GMA (random terpolymer of ethylene, acrylic ester and glycidyl metacrylate) functionalized polymers at dif...
