MECHANICAL PROPERTIES OF DENTAL COMPOSITE MATERIALS REINFORCED WITH MICRO AND NANO-SIZE Al2O3 FILLER PARTICLES
Abstract: Composite specimens were prepared by dispersion of various amounts of nano-sized Al2O3 fillers in a monomer system containing 60% Bis-GMA and 40% TEGDMA. For comparative purposes, composite samples containing micrometer size Al2O3 fillers were also prepared following the same procedure. The mechanical properties of the light- cured samples were assessed by three-point flexural strengt...

Composite specimens were prepared by dispersion of various amounts of nano-sized Al2O3 fillers in a monomer system containing 60% Bis-GMA and 40% TEGDMA. For comparative purposes, composite samples containing micrometer size Al2O3 fillers were also prepared following the same procedure. The mechanical properties of the lightcured samples were assessed by three-point flexural strength, diametral...
متن کاملGrinding of Aluminium-Based Metal Matrix Composites Reinforced with Al2O3 or SiC Particles
This paper presents results obtained from the grinding of aluminium-based metal matrix composites reinforced with either aluminium oxide (Al2O3) or silicon carbide (SiC) particles using grinding wheels made of SiC in a vitrified matrix or diamond in a resin-bonded matrix. The study used grinding speeds of 1100–2200 m min , a grinding depth of 15 m for rough grinding and 0.1–1 m for fine grindin...
متن کاملMicrostructure and Mechanical Properties of Mg-5Nb Metal-Metal Composite Reinforced with Nano SiC Ceramic Particles
In this work, a Mg-5Nb metal–metal composite was reinforced with nano SiC (SiCn) ceramic reinforcement of varying volume fractions, using the disintegrated melt deposition technique. The extruded Mg-5Nb-SiCn composites were characterized for their microstructure and mechanical properties. Based on the results obtained, it was observed that the volume fraction of nano-SiC reinforcement played an...
متن کاملSynergistic strengthening effect of nanocrystalline copper reinforced with carbon nanotubes
In this study, a novel multi-walled carbon nanotubes reinforced nanocrystalline copper matrix composite with super high strength and moderate plasticity was synthesized. We successfully overcome the agglomeration problem of the carbon nanotubes and the grain growth problem of the nanocrystalline copper matrix by combined use of the electroless deposition and spark plasma sintering methods. The ...
