Abstract The purpose of this article is to review the use of fiber reinforced composites in fixed partial dentures. Fiber reinforced materials have highly favourable mechanical properties and their strength to weight ratios are superior to those of most alloys. When compared to metals they offer many other advantages as well, including non-corrosiveness, translucency, good bonding properties and ease of repair. They also offer the potential for chairside and laboratory fabrication. How to cite this article Ashwini W, Veena SP, Swati B.

Voids are inevitable in the fabrication of fiber reinforced composites and have a detrimental impact on mechanical properties of composites. Different void contents were acquired by applying different vacuum bag pressures. Ultrasonic inspection and ablation density method were adopted to measure the ultrasonic characteristic parameters and average porosity, the characterization of voids' distribution, shape and size were carried out through metallographic analysis. Effects of void content on the tensile, flexural and interlaminar shear properties and the ultrasonic characteristic parameters were discussed. The results showed that, as vacuum bag pressure went from -50kPa to -98kPa, the voids content decreased from 4.36 to 0.34, the ultrasonic attenuation coefficient decreased, but the mechanical strengths all increased.
