Flexural Strength of Polymethyl Methacrylate Repaired with Fiberglass
Objectives The purpose of this experimental study was to discover a method to increase the strength of repaired polymethyl methacrylate (PMMA) samples. Materials and Methods In this experimental study, 40 specimens with the dimensions of 65×10×2.5mm3 were fabricated using heat-curing acrylic resin. Sixteen specimens were repaired with fiberglass and self-curing PMMA, while 16 samples were rep...
متن کاملdetermination of some physical and mechanical properties red bean
چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولSynthesis and thermal characterization of polymethyl methacrylate
PMMA with molecular mass (PMMA Mw: 1.2×105) was synthesized through AIBN initiated free radical polymerization methyl methacrylate at 100 ± 1°C.The synthesized polymer was characterized through GPC coupled with RI detector in presence of THF as mobile phase at 1.0 mL/ min and simultaneous TG-DTA-DTG in nitrogen. TG data were used to investigate the non-isothermal kinetics of solid-state decompo...
متن کاملEvaluation of the Mechanical Properties and Drug Permeability of Chitosan/Eudragit RL Composite Film
OBJECTIVES The aim of this study was to design and evaluate a chitosan-based film that has properties required for successful wound dressing, and can control drug penetration and maintenance time in the location. METHODS Several formulations of a film containing chitosan (3%) and different concentrations of Eudragit RL (0.5%, 1%, and 1.5%) were prepared using the casting/solvent evaporating t...
متن کاملEffect of Nanoclay on Thermal Conductivity and Flexural Strength of Polymethyl Methacrylate Acrylic Resin
STATEMENT OF THE PROBLEM The mechanical and thermal properties of polymethyl methacrylate (PMMA) acrylic resin should be improved to counterweigh its structural deficiencies. PURPOSE The aim of this study was to compare the flexural strength and thermal conductivity of conventional acrylic resin and acrylic resin loaded with nanoclay. MATERIALS AND METHOD The methacrylate monomer containing...
