Effects of fiber properties on shrinkage of fiber/PMMA composite-based bone cements

Abstract

Fiber/polymethylmetacrylate (PMMA) composite bone cements were prepared with various fiber types (polyester and kevlar) in %1, 2 and 3 volumes. The shrinkage of the fiber/PMMA composite patterns were then calculated among 150 days. Results indicated that fiber type and also length and volume effected the shrinkage behaviour of the fiber/PMMA composite patterns.
