Abstract

A theoretical and experimental investigation of porous powder—fiber materials based on copper powder and fibers with a layered distribution of components was carried out. Maximum and average pore sizes, permeability coefficients, and efficiency parameters as functions of pressing pressure, powder particle size, and relative thickness of the fiber layer were investigated. It was shown that the use of components with certain dimensions permits the fabrication of materials with a high pore size gradient (up to 12 times) in a thickness of material that considerably increases the efficiency parameter E relative to that in porous powder and porous fiber materials.
