(EN) CONDUCTIVE NONWOVEN FABRIC
(FR) TISSU NON-TISSÉ CONDUCTEUR
(JA) 導電性不織布
Abstract
(EN)
The purpose of the present invention is to provide a material having higher radio wave absorption characteristics (high absorption, low reflection) even at high frequencies. Provided is a conductive nonwoven fabric having a metal layer on at least one surface thereof, and having a sheet resistance of 200-600 Ω/□ and a density of 2.0×104 to 8.0×105 g/m3.
(FR)
La présente invention vise à fournir un matériau ayant des caractéristiques d'absorption d'ondes radio supérieures (absorption élevée, faible réflexion) même à des fréquences élevées. L'invention concerne un tissu non-tissé conducteur ayant une couche métallique sur au moins une surface de celui-ci, et ayant une résistance de couche de 200 à 600 Ω/□ et une densité de 2,0 × 104 à 8,0×105 g/m3.
(JA)
高周波に対してもより高い電波吸収特性(高吸収性、低反射性)を備える材料を 提供すること。 少なくとも一方の面に金属層を有する導電性不織布であって、シート抵抗が200~600Ω/□ であり、且つ密度が2.0×10~8.0×10g/mである、導電性不織布。
