Abstract

The effect of nanofibrous cellulose and polyvinylpyrrolidone with different molar masses in the concentration range of 0.003–3 wt % on the compressive strength and fracture behavior of fabricated ice composites in comparison with pure freshwater ice is studied. It is found that, with an increase in the mass fraction of the filler from 0.3 to 1 wt % for all ice composites, a transition from brittle to ductile fracture occurs. The maximum strengthening effect is achieved with the addition of 0.3 wt % of the filler to ice. The highest compressive strength is observed in the ice composites with cellulose nanofibers and long polyvinylpyrrolidone molecules, exceeding the compressive strength of pure ice by approximately 1.7 times.
