Title:
ELECTROMAGNETIC SHIELDING MATERIAL AND METHOD FOR MOLDING THE SAME
Document Type and Number:
Japanese Patent JPH05269796
Kind Code:
A
Abstract:

PURPOSE: To obtain an electromagnetic shielding material increased in the content of a conductive material, excellent in electromagnetic shielding characteristics, having high electromagnetic shielding capacity, capable of being formed into a complicated shape such as a three-dimensional structure, capable of being mass-produced and excellent even from an aspect of cost.

CONSTITUTION: A conductive fiber sheet A formed by making a conductive material fibrous is preliminarily arranged between molds 1 along with a matrix sheet B and, after injection molding is subsequently performed by an injection molding machine 8, the matrix sheet B is removed. By this constitution, the conductive fiber sheet A is transferred to the surface of a resin structure at the time of injection molding to obtain an electromagnetic shielding material having an electromagnetic shielding layer formed thereon. In the first place, since the electromagnetic shielding layer is formed by transfer at the time of injection molding, the content of the conductive fiber sheet A, that is, the conductive material can be enhanced and, in the second place, since injection molding is utilized, the electromagnetic shielding material having a complicated shape can be obtained and the mass production thereof is possible.
