Abstract
The aim of this paper was to estimate the effect of moisture and temperature on the
flexural properties of the epoxy filled with single and hybrid carbon nanofillers (CNTs and
CNFs) and to reveal the most environmentally stable NC. Water absorption at 70 °C until
equilibrium moisture content and heating at 70 °C for 4 weeks were followed by freezing at -
20 °C for 8 weeks. Microstructural characterization of optical images revealed homogeneous
dispersion of all carbon nanofillers in the epoxy resin at microscale. Positive nanofiller effects
were found for sorption, flexural and thermophysical characteristics of the epoxy resin. The
most environmentally stable NC was epoxy filled with 0.1 wt. % of CNTs/CNFs hybrid, which
had the lowest effect of temperature and moisture on mechanical characteristics, along with the
lowest equilibrium water content and diffusivity.
