This study evaluated tensile bond strength of a denture soft lining material to a poly (methylmethacrylate) (PMMA) denture base resin subjected to different surface treatment modalities and thermocycling. The materials tested were a silicone-based liner, Molloplast B (R), and a heat-cured denture base resin, Meliodent (TM). The denture soft lining material was packed against cured PMMA base resin, which was smoothed; sandblasted with 250-mu m Al2O3 particles; or lased with a KTP laser; or against uncured PMMA dough (n = 10). In each group, five specimens were thermocycled in a water bath (5-55 degrees C; 3000 cycles) before testing, whereas the other five were directly tested after 24 h. A tensile test was performed using a universal testing machine. Data showed that different treatment modalities of resin surfaces affected adhesion between these two materials and the highest bond values were recorded for cured/smoothed samples under each condition tested. Thermocycling of specimens had no significant reducing effect on measured bond strength values.

Effect of Maleic Anhydride Pretreatment on Tensile Bond Strength of a Silicone Soft Liner to a Denture Base Polymer DEMİR, HAKAN; SOYGUN, KORAY; DOĞAN, ARİFE; Keskin, Selda; DOĞAN, ORHAN MURAT; Bolayir, Giray (2011-10-01) Purpose: To determine the effect of resin surface treatment with dissolved maleic anhydride in butanone added into primer on the tensile bond strength between an acrylic denture base resin and a silicone soft liner.
THE INFLUENCE OF MANUFACTURING DEFECTS ON STRUCTURAL PERFORMANCE OF COMPOSITE OVERWRAPPED PRESSURE VESSELS Yurdakul, Kıvanç; Gürbüz, Rıza; Department of Metallurgical and Materials Engineering (2022-2-04) In this study, the influence of defects that are occurred in manufacturing operations of filament wound composite overwrapped pressure vessels on burst pressure is investigated experimentally. Firstly, material characterization methods such as tensile testing and fiber volume fraction testing of carbon/epoxy composite specimens are completed. Following determining of different layer configurations for small scale composite pressure vessels, manufacturing and burst testing of vessels are accomplished. Ef...
The effects of some methacrylate monomers used as liquid component on tensile and flexural strengths of a poly (methyl methacrylate) denture base resin Do'an, Orhan Murat; Bolayir, Giray; Keskin, Selda; Boztug, Ali; Do'an, Arife; Bek, Buelent (2006-12-01) This study was conducted to observe the effect of different monomers on tensile and flexural strengths of poly (methyl methacrylate) (PMMA) denture base resin when they were used as a liquid component. A conventional heat-cured denture base polymer powder was mixed with ethyl, isobutyl and tert-butyl methacrylate monomers, respectively. After the polymerization process was completed, the tensile and flexural strength values of these specimens were compared with those that of PMMA resin specimens polymerized...
Peel Bond Strength of Two Silicone Soft Liners to a Heat-cured Denture Base Resin DEMİR, HAKAN; DOĞAN, ARİFE; DOĞAN, ORHAN MURAT; Keskin, Selda; Bolayir, Giray; SOYGUN, KORAY (2011-12-01) Purpose: This study investigated the peel strength of two different soft liners to a polymethylmethacrylate (PMMA) denture base resin before and after thermocycling.
The effect of magnisium to sulfur ratio on the graphite morphology of graphite cast iron produced at differrent section thicknesses ELMABROUK, Omar; ERFAN, Osama M.; Kalkanlı, Ali (2011-09-18) This paper is concerned with the investigation of the effect of magnesium to sulfur ratio on the graphite morphology and estimation of the ranges of this ratio use to produce graphite cast iron at different section sections. The main factors affecting shape of graphite cast iron are the metallurgical structures and the section thicknesses. Cast iron of different shapes of graphite particles directly affect its thermo-mechanical properties. The nodular shape of these graphite particles such as in ductile cas...
