摘要

本文研究了由铜纤维和铜网增强纤维制成的多孔结构的力学性能的复杂性，以评估纤维结构的粘接强度和用于换热器结构的被测元件之间的内聚性。所有试样均以宏观开孔率表征。用金相技术对接头的内部组织进行了分析。给出了各层之间连接的统计关系。讨论了铜“氢病”生产工艺的副作用。

ASPECTS OF COMPLEXITY OF METAL-FIBROUS MICROSTRUCTURE FOR THE CONSTRUCTION OF HIGH-PERFORMANCE HEAT EXCHANGERS: ESTIMATION OF ADHESIVE STRENGTH

The paper deals with aspects of the complexity of mechanical properties of porous structures made from copper fibers and fibers reinforced with copper meshes to assess the adhesive strength of the fibrous structure and the cohesion between the components of the tested elements used for the construction of heat exchangers. All of the tested samples were characterized by macroscopic open porosity. The internal structure of the obtained connections was analyzed by metallographic techniques. Statistical relations of the connections made between the layers have been provided. The side effects of the production technology related to the “hydrogen disease” of copper have been discussed.
