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 کاملWhisker alignment of Ti±6Al±4V/TiB composites during deformation by transformation superplasticity
We examine the eect of 10 vol.% TiB whisker reinforcement on transformation superplasticity of Ti±6Al±4V, induced by thermal cycling about the a/b phase transformation range of the matrix under a uniaxial tensile stress. During superplastic deformation, the whiskers gradually align along the external loading axis, as measured by electron back-scattering diffraction of deformed specimens. The c...
متن کاملThe mechanical behavior dependence on the TiB whisker realignment during hot-working in titanium matrix composites
Low-cost TiB whiskers reinforced titanium matrix composite (TMCs) was fabricated with enhanced mechanical performances using in situ technologies and hot working. Morphologies observation indicates that needle-like TiB whiskers with a hexagonal transverse section grow along the [010] direction due to B27 crystal structure and its growth mechanism. Mechanical properties tests show that the mecha...
متن کاملANX-RAY FRACTOGRAPHY STUDY OF A SINTERED COMPOSITES SYSTEM OF Al204 Sic (WHISKER)
X-ray methods were used to measure the residual stress near a fracture surface of a sintered composite system of A&03/ Sic. A specimen bent at three points with different notch radii was used to measure h-acture toughness. Effects of the notch radii on the stress intensity factor Kp were measured during the initiation of the crack. Experimental results agreed with fracture mechanics theory.
