Abstract

Provided is a copper fiber nonwoven fabric having a bonding portion between copper fibers, and in the relationship between compressive stress and strain, is provided with a first region exhibiting plastic deformation and a second region exhibiting elastic deformation in which compressive stress is higher than the first region. Alternatively, the copper fiber nonwoven fabric has a bonding portion between copper fibers, and in the relationship between compressive stress and strain, has a region exhibiting elastic deformation, wherein the region exhibiting elastic deformation has an elastic deformation region before an inflection portion a, the inflection portion a, and an elastic deformation region after the inflection portion a.

Claims

exact text as granted — not AI-modified
1 . A copper fiber nonwoven fabric having a bonding portion between copper fibers and,
 in the relationship between compressive stress and strain,   is provided with a first region exhibiting plastic deformation and,   a second region exhibiting elastic deformation in which compressive stress is higher than the first region.   
     
     
         2 . The copper fiber nonwoven fabric according to  claim 1 , having an inflection portion a in the second region exhibiting elastic deformation where strain exhibits inflection in response to compressive stress. 
     
     
         3 . A copper fiber nonwoven fabric having a bonding portion between copper fibers and,
 in the relationship between compressive stress and strain, has a region exhibiting elastic deformation, wherein   the region exhibiting elastic deformation has an elastic deformation region before an inflection portion a, the inflection portion a, and an elastic deformation region after the inflection portion a.
