POLYMER TESTING, vol.23, no.3, pp.343-346, 2004 (SCI-Expanded)
Various microhardness test methods with different indentation loads and dwell times have been used to evaluate the hardness of composite materials. However, there is still no agreement on the ideal test method for composites. The aim of this Study was to determine the influence of different indentation load and dwell time on Knoop Hardness Number (KHN) of three different kinds of light-cured composites.
