Pore Size Dependence of Compressive Behavior and Energy Absorption Properties of Porous Copper

Abstract:

Porous copper with an open-cellular structure was prepared basing on space-holder method. Depending on the volume fraction and size of the space holding particle, the porosity can be varied in a wide range of 40-85%, and the pore size can be tailored from micron to millimeter in order. The effects of pore size on compressive behavior and energy absorption properties were investigated by quasi-static compression measurement. The results showed that the pore size shows a significant effect on compressive behavior and energy absorption properties. The compressive stress-strain curves were increased with increasing the pore size. The energy absorption capacity and energy absorption efficiency were greatly improved at the same strain, when the pore sizes transferred from micron to millimeter in order, indicating a more desirable energy absorption property of larger pore size.
