| Popis: | 1. Materials from metal fibers are characterized by numerous interfiber contacts, thanks to which they possess high electrical conductivity. At high porosities the electrical conductivity is up to 20% of the real conductivity of the corresponding nonporous materials in the as-pressed condition and not less than 55–70% of the ideal electrical conductivity of porous materials after sintering. 2. The thermal conductivity of fiber materials changes only little as a function of temperature. With rise in temperature in the range 100–1000°C it increases only two- to threefold. |
