Elastic modulus of experimental bioactive glass composites

摘要

Elastic moduli, (n=3) for eight composite systems were determined using an ultrasonic method. Mean values for glass composite ranged from 14.81+-0.14 GPa for silane treated filler to 10.84+-0.35 GPa for non-silane treated material. Mean value for Young's modulus of low temperature fired inorganic silane treated filler was 11.96+-0.05 GPa. Using a Kokubo biomimetic method the eight composite substrates were also evaluated to determine their ability to deposit calcium, phosphorus and sodium on their surface when stored in a dynamic 1.0 concentration of SBF solution for 30 days
