Ceramic whisker reinforcement of dental resin composites.
Resin composites currently available are not suitable for use as large stress-bearing posterior restorations involving cusps due to their tendencies toward excessive fracture and wear. The glass fillers in composites provide only limited reinforcement because of the brittleness and low strength of glass. The aim of the present study was to reinforce dental resins with ceramic single-crystalline...
متن کاملSTRENGTH AND FRACTURE TOUGHNESS OF WHISKER REINFORCED DENTAL RESIN-BASED COMPOSITES
Enhancing the properties of dental resin composites is of interest to researchers. The objective of the present investigation was to improve the strength and fracture toughness of dental composites via addition of silicon carbide whiskers and substitution of commonly used filler materials with stabilized zirconia ceramic powder. It was also intended to study the effect of powder- to- whisker ra...
متن کاملExperimental study of fracture mechanics in the aluminum matrix composites containing Fifteen percent silicon carbide particles
In this investigation ‚the fracture toughness of A356 containing15%SiC composite was studied. Al/SiC composites have been considered because of their mechanical and erosion properties .Low fracture toughness in Al/SiC as compared with Aluminium alloys is one of its disadvantage. In this study at first A356 alloy was melted in a smelting electrical furnace then poured into the mould. A356-15% Si...
متن کاملPreparation and evaluation of geopolymer composites containing alumina particles at ambient temperature and after heating
In this research, geopolymer composites were prepared using metakaolin along with silica fume and potassium hydroxide as alkaline activators and alumina particles. The effect of alumina particle size to achieve castable microstructure and their mechanical properties were investigated. Different Si:Al mole ratio (1.5, 2, 2.5 and 3) and K:Si mole ratio (0.20, 0.25, 0.33) were formulated and the s...
