pores. The overall porosity and porosity of open pore of the sintered porous magnesium increase with the increase of added spacer material, while decrease with the increase of the molding stress. The mechanical properties of sintered porous magnesium increase with decreasing addition of spacer material and increasing molding stress.

Effect of porous structure on mechanical properties of C/PLA/nano-HA composites scaffold LIAO Xiao-ling(廖晓玲)1,2, XU Wen-feng(徐文峰)3, WANG Yuan-liang(王远亮)1, JIA Bi(贾 碧) 2, ZHOU Guan-yu(周冠瑜)2...; Abstract: Nonporous and porous C/PLA......
, the loading conditions of these porous materials were further studied for various strut failure modes from different loading. The results show that these failure modes are relative to the material indexes, porosity and loading magnitude, and these relationships can be correspondingly expressed by the specific mathematical equations.
