Characterization of styrene butadiene rubber and microwave devulcanized ground tire rubber composites
Karabörk, Fazliye; Pehlivan, Erol; Akdemir, Ahmet (Walter de Gruyter GmbH, 2014)Ground tire rubber (GTR) was devulcanized by microwaves at the same heating rate (constant power) and different times of exposure. The devulcanized rubber (DVR) and untreated GTR were characterized physically and thermally. ... -
Effect of Silica/Graphene nanohybrid particles on the mechanical properties of epoxy coatings
Özcan, Ümit Esra; Yazman, Şakir; Akdemir, Ahmet; Karabörk, Fazliye (Springer Berlin Heidelberg, 2019)Epoxy resins are used as coating materials, but the practical use of epoxy coatings in industries is limited due to their weak mechanical properties. In the present paper, different amounts of silica nanoparticles ( SiO2) ... -
Effects of nano reinforcing/matrix interaction on chemical, thermal and mechanical properties of epoxy nanocomposites
Yazman, Şakir; Uyaner, Mesut; Karabörk, Fazliye; Akdemir, Ahmet (SAGE Publications Ltd, 2021)This article investigates the impact of addition various types of nanoparticles with different structural, dimensional, and morphological properties on the interphase region formed between the particle/matrix and the curing ... -

Karabörk, Fazliye; Akdemir, Ahmet (Pamukkale Üniversitesi, 2015)Oda sıcaklığında öğütülen atık taşıt lastiği tozu mikrodalga yöntemiyle devulkanize edilmiştir. İşlemde devulkanizasyon ajanı olarak, kükürt bağlarının (S-S) koparılmasında etkinliği çeşitli çalışmalarda ortaya konulmuş ... -
Friction and wear behavior of styrene butadiene rubber-based composites reinforced with microwave-devulcanized ground tire rubber
Karabork, Fazliye; Akdemir, Ahmet (John Wiley and Sons Limited, 2015)In this work, the tribological properties of a new material obtained by revulcanization with styrene butadiene rubber (SBR)and devulcanized ground tire rubber (GTR) were investigated. GTR was devulcanized using the microwave ... -
Improvement of anti-corrosion performance (surface and near the cut edge) and mechanical properties of epoxy coatings modified with nano, micro and hybrid ZnO particles
Kabaoğlu, Emre; Karabörk, Fazliye; Balun Kayan, Didem; Akdemir, Ahmet (SAGE Publications Ltd, 2023)Composites were formed by incorporating nano, micro and hybrid-ZnO particles into the epoxy matrix at the same loading levels (3%) and applied at 90 μm thickness on the galvanized steel substrate using a film applicator ... -
Investigation effect of zinc nanoparticles on the mechanical and anticorrosion properties of epoxy coatings on stainless steel surface
Apsak, Merve; Akdemir, Ahmet; Karabörk, Fazliye; Yazman, Şakir (Gazi Üniversitesi, 2021)In this study, effects of zinc nanoparticles (ZNPs) on the mechanical properties of epoxy coatings and anticorrosion behavior on the stainless steel were investigated. The nanocomposites (NCs) were obtained by adding ZNPs ... -
Investigation of mechanical properties of SBR in which added devulcanized waste tire rubber with various proportions of DPDS
Karabörk, Fazliye; Akdemir, Ahmet (Pamukkale University, 2015)The waste tire rubber that had been grounded in room temperature was devulcanized by using the microwave method. As the devulcanizing agent, diphenyldisulfide (DPDS), the efficiency of which in the breaking off of sulfur ... -
