摘　　要：Using forming-knitting technology and organic materials, copper foam with high porosity (>80%) and open-pore structure was successfully prepared. According to the method of immersion, the technical characteristics of metal paste performance and influence factors of sinter process were discussed. The pore morphology and compressibility of copper foam were detected simultaneously, and the structural property of copper foam prepared by the process of once-infiltrating was compared with the one of copper foam prepared by the process of twice-infiltrating. The results show that pH value of metal paste has a large influence on rheological properties of slurry. By twice-infiltrating process, the microstructure of copper foam was altered. In case of the porosity dropping indistinctly, the compression stress of copper foam platform was raised from 0.5 MPa to 1 Mpa which was of great significance to improve the energy absorption capacity of the material.Using forming-knitting technology and organic materials, copper foam with high porosity （ 〉 80 % ） and open-pore structure was successfully prepared.
