METALLIC FIBER NON-WOVEN FABRIC AND ITS PRODUCTION METHOD.

摘要

This invention relates to a production method of a metallic fiber non-woven fabric having core materials obtained by depositing a metal by plating or the like method on a core material non-woven fabric obtained by combining mutually core materials such as carbon fibers by a binder to prepare a metal coated core material non-woven fabric and then annealing the metal coated non-woven fabric, to a production method of a hollow metallic fiber non-woven fabric obtained by removing the core material non-woven fabric from the metal coated core material non-woven fabric described above and further to a metallic fiber non-woven fabric having the core materials and a hollow metallic fiber non-woven fabric obtained by these methods. The resulting metallic fiber non-woven fabric has high strength at the bond portions of the metallic fibers and has a high void ratio.
