Conclusions

  1. 1.

    The relationship between the modulus of elasticity E and relative density ϑ of fibrous metals is described by Eq. (2), in which the minimum value of the power m is close to 2.

     
  2. 2.

    The contact ultimate strength obc=ob/α=obEc/E for fibrous copper and stainless steel, determined from Eq. (1), was independent of porosity within the limits of experimental error and had a value corresponding to the σb of the nonporous metal in the annealed state. This indicates that the modulus of elasticity E is a basic characteristic for evaluating the contact cross-section and strength of porous fibrous metals.

     
  3. 3.

    We obtained data on the damping decrement as a function of the density of porous fibrous metals.
