Structural Integrity Studies in Particulate Composites by Means of Thermal Capacity Measurements

Abstract
Glass-transition temperatures Tg for iron-epoxy composites were deter mined from heat-capacity measurements. The effect of several parameters, such as the heating rate, the filler-volume fraction and the particle diameter on Tg was investigated and conclusions concerning the thickness of the boun dary interphase were derived. Tg-values obtained from TMA-measurements were compared to the respective values obtained from DSC-measurements.
