Dynamic mechanical properties of poly(methyl methacrylate) (PMMA) reinforced with glass fibers were investigated. The composite used as dental base material contained other additives for different purposes to give the same appearance as natural dentals. The fiber-polymer bonding and orientation of fibers in polymer matrix are very important in the application of the product. To see that, the fibers were treated with silane and compared with untreated fibers. The commercial polymer and monomer used were the heat-cured type. However, in addition to heat curing, gamma-radiation was also used in curing. This gives much improved material in terms of mechanical properties. The voids, which cause mechanical failure in the material, will be minimal in number with irradiation curing. The results showed that the orientation of all fibers were not regular. This could be observed from the micrographs and DMA behaviors of samples. (C) 2002 Wiley Periodicals, Inc.

Flexible and conducting composites of polypyrrole and polydimethylsiloxane
Cahmak, G; Kucukyavuz, Z; Kucukyavuz, S (Wiley, 2004-07-15)
Conductive and flexible polydimethylsiloxane (PDMS)/polypyrrole (PPy) composites were synthesized electrochemically. Electrochemical syntheses were performed at +1.10 V by using p-toluene sulfonic acid (PTSA) as supporting electrolyte and water as solvent. Composites were characterized by cyclic voltammetry, thermogravimetric analysis, differential scanning calorimetry, scanning electron microscopy, and Fourier transform infrared spectroscopy. Conductivity measurements and mechanical tests were also perform...
Poly(methyl methacrylate) hybrid syntactic foams with hollow glass microspheres and polyhedral oligomeric silsesquioxanes
Ozkutlu, Merve; Dilek Hacıhabiboğlu, Çerağ; Bayram, Göknur (Wiley, 2019-08-10)
The study aims to produce poly(methyl methacrylate) (PMMA)-based lower density syntactic foams with hollow glass microspheres (HGMs) and to improve their mechanical properties by the addition of polyhedral oligomeric silsesquioxanes (POSSs) while maintaining the thermal properties of the neat polymer. First to understand the effect of POSS addition, PMMA-POSS composites with octaisobutyl and octaphenyl POSS were produced through extrusion. Higher relative flexural and impact strengths were obtained with POS...
Mechanical properties of soft liner-poly(methyl methacrylate)-based denture material
Usanmaz, Ali; Latifoglu, MA; Dogan, A; Akkas, N; Yetmez, M (Wiley, 2002-07-18)
In this study, the mechanical properties of two different permanent soft lining materials and their bonding to poly(methyl methacrylate) (PMMA) were compared. Both of the soft liners were heat-cured commercial materials. The polymerization was carried out by conventional methods suggested by manufacturer, and the curing was done at the temperature of boiling water for 5, 15, 25, and 35 min. The sample groups were tested in the computer-aided tensile-testing machine at a rate of 2 mm/min. The slow rate helps...
Improved adhesive properties and bonding performance of HTPB-based polyurethane elastomer by using aziridine type bond promoter
Gercel, BO; Üner, Deniz; Pekel, F; Özkar, Saim (Wiley, 2001-05-02)
The effect of two aziridine-type bond promoters on adhesive and mechanical properties of a hydroxyl terminated polybutadiene-based elastomeric liner used in solid propellant rockets was investigated by varying the concentration to determine the optimum value. The performance of butyleneiminetrimesoylaziridine (BITA) was compared with that of tris[1-2-methylaziridinyl]phosphine oxide (MAPO) in the elastomeric liner of otherwise the same composition. The adhesive performance of the elastomer to the composite ...
Physical Properties and Cure Characteristics of Natural Rubber/Nanoclay Composites with Two Different Compatibilizers
Dogan, Mehmet; Oral, Demet Dengiz; Yilmaz, Betul; Savu, Melih; Karahan, Selcuk; Bayramlı, Erdal (Wiley, 2011-08-05)
The effects of epoxidized natural rubber (ENR) and maleic anhydride-grafted polybutadiene (PB-g-MA) as compatibilizers to rubber formulations with and without organo-modified layered silicates are investigated. The physical properties and curing characteristics of composites are studied by moving die rheometer, rubber process analyzer, tensile, tear, and hardness testing. The state of organoclay intercalation was determined by X-ray diffraction method. The addition of compatibilizers, especially ENR 50, res...
