The investigation of nanofluidic energy absorption system based on high porosity aerogel nano-materials
Abstract
There is an increasing interest in Nanofluidic Energy Absorption System (NEAS) due to its high energy absorption density. This work investigated energy absorption characteristics of NEAS based on aerogel. The pressure-volumetric strain curves of the aerogel nanofluidic system are acquired along with those of the zeolite nanofluidic system through the designed testing device. The microscopic responses of both nanofluidic systems under external loads are demonstrated by molecular dynamics simulations. The energy absorption performances of collapse tubes filled with NEAS based on aerogel, zeolite and silica gel, respectively, are compared through finite element analysis. The result shows that the aerogel nanofluidic system has great energy absorption density (EAD), and has a remarkable prospect in the field of anti-crash and buffers. The research promotes further exploration of mechanism and potentials of such new type of energy absorption material for use in aerospace field.
