Aging Effects of Aqueous Environment on Mechanical Properties of Calcium Carbonate-Modified Epoxy Resin.

From the analysis of the compressive maximum strength data reported in Figure 8 b, it can be repeated what already observed in the case of immersion in demineralised and distilled water ( Figure 4 b and Figure 6 b, respectively), that is, the exposure to spring water brought about a slight decrease in the compressive maximum strength of CaCO 3 -filled E5/TFF/100:26 compounds; the exposure time had a limited effect on the maximum strength only up to 6 months of aging; the effect of the filler load is almost insignificant; irrespective to the filler content, the aged CaCO 3 -modified E5/TFF/100:26 compounds achieved values of mechanical strength not much lower than that recorded for unaged E5/TFF/100:26 control.
