Influence of graphene oxide on flexural strength, modulus of elasticity and micro hardness of poly ethyl methacrylate
Background and Aim: graphene is a two-dimensional nanostructure consist of a single layer of SP2 carbon atoms that arranged by covalent bonds in a hexagonal bee web. The reinforcement by GO is due to functional groups that lead to strong interaction, dispersion and stress distribution. Due to lower mechanical properties and strength of PEMA than PMMA, we evaluate effect of GO on mechanical prop...
متن کاملThe effect of TiO2 and SiO2 nanoparticles on flexural strength of poly (methyl methacrylate) acrylic resins.
PURPOSE TiO(2) and SiO(2) nanoparticles are products of nanotechnology which have been incorporated to acrylic resins (AR) in order to induce antimicrobial properties. However, as additives they can affect the mechanical properties of the final product. The aim of this study was to survey the effects of TiO(2) and SiO(2) nanoparticles on flexural strength (Fs) of poly (methyl methacrylate) acry...
متن کاملThe effect of SiO2 nano-filler addition into heat-cured poly methyl methacrylate on three-point flexural strength
Background and Aims: Poly methyl methacrylate (PMMA) is still the most commonly used material in prosthetic dentistry. However, there are problems with the mechanical properties of this type of material including low flexural strength. Addition of nanoparticles into the polymer is one way to improve the mechanical properties of acrylic resin. In the present study, the effect of silicon dioxide ...
متن کاملFlexural modulus, flexural strength, and stiffness of fiber-reinforced posts.
BACKGROUND The radiopacity degree of posts is not enough for adequate visualization during radiographic analyses. Glass fiber post with stainless steel reinforcement has been fabricated in an attempt to overcome this limitation. AIM This study was designed to determine the influence of this metal reinforcement on the post mechanical properties. MATERIALS AND METHODS This study evaluated fle...
متن کاملFlexural 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...
