摘要：

A novel porous metal fiber sintered sheet (PMFSS) with high porosity was fabricated by the solid-state sintering method of copper fibers. In this study, the shear experiments were conducted to investigate the effect of porosity and sintering parameter on the shear properties of PMFSS. The typical shear stress-strain plot of PMFSS was obtained based on a larger number of shear test results. The shear fracture process of PMFSS was then divided into three steps: linear elastic stage, plastic deformation stage, and shear fracture stage. The shear strength was found to be decreased with increasing porosity ranging from 70% to 90% when the PMFSS was produced under the same sintering parameter. Moreover, the influence of sintering parameter on shear strength of PMFSS was also investigated. Our experimental results showed that the increase of the sintering temperature or holding time would give rise to the increase of shear strength of PMFSS.
