Highlights Both three- and four-point bending setup were established. Similar three stages in three- and four-point bending fracture process were observed. The bending strength was decreased with increasing porosity. Higher sintering temperature produced higher bending strength. The extension of holding time slightly affected the bending strength.
Abstract 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, both three- and four-point bending setup were established to characterize the bending properties of PMFSS. Similar three stages in the three- and four-point bending fracture process were observed for the PMFSS with 80% porosity sintered at 900°C for 60min. Comparing with the three-point bending, it is found that much smaller bending force was obtained in the four-point bending test under the same displacement conditions. Moreover, the porosity and sintering parameters were also varied to investigate the influence on the bending properties of PMFSS. Both three- and four-point bending strength were found to be decreased with increasing porosity ranging from 70% to 90%. Higher sintering temperature produced higher bending strength for the PMFSS sintered in the temperature range of 700–1000°C. Besides, the extension of holding time also could slightly affect the bending strength.
