RADIO ABSORBING MATERIAL

Title:

RADIO ABSORBING MATERIAL

Document Type and Number:

Japanese Patent JPS61268759

Kind Code:

A

Abstract:

PURPOSE: To obtain the titled material with absorption characteristics stable to temperature variation, usable in high-frequency zone, by incorporating a polymeric resin with transition metal element-contg. fibrous noncrystalline alloy or either granular or foil-shaped transition metal element (such as iron or nickel)-contg. noncrystalline alloy.

CONSTITUTION: The objective material can be obtained by incorporating (A) a polymeric resin 1 with (B) transition metal element (such as iron or nickel)- contg. fibrous noncrystalline alloy 2. For such ratio absorbing material as to be effective for both electric and magnetic field components of electromagnetic wave, at least one kind of granular or foil-shaped noncrystalline alloy 3 containing crystalline transition metal element such as iron or nickel is preferably dispersed.
