Abstract
Intensive dynamic loadings are the main threats to the structural damage of protective structures and inner
equipment, which has attracted a lot of attention in the field of advance impulsive resistance. Nanofluidic
liquid foam (NLF) has become a novel and efficient energy absorption system due to its reusable energy
absorption, ultra-high load transfer, and high energy absorption ratio. In order to solve the current problem
that the energy absorption mechanism of NLF is still unclear, this paper conducted a systematic
experimental study on the dynamic compression and energy absorption behaviours of NLF. The quasi-static
cyclic compression experiments with different liquid types and loading rates were carried out, which
revealing the effect of solid-liquid properties on the infiltration pressure and clarifying the strain rate
insensitivity of NLF. Also, the main parameter properties affecting the energy absorption density and the
repeatable usage rate of NLF are obtained. Moreover, the dynamic impact experiments were carried out by
a separated Hopkinson pressure bar (SHPB) experimental setup, the influence laws of different loading rates
on the macroscopic mechanical response and microscopic infiltration behavior of NLF are discussed. It is
found that the mechanical properties of NLF materials under dynamic impact, although still based on their
nano-scale solid-liquid infiltration behaviour, are not exactly the same as the influence mechanism under
quasi-static conditions. The results also indicate that gas molecules have a similarly significant effect on the
liquid infiltration behavior and energy absorption efficiency of the NLF under high strain rate impacts. The
research fills the lack of study on dynamic infiltration and energy absorption characteristics, and provides
theoretical reference for the research and development of various nanofluid systems.
