Abstract

The present invention relates to a nonwoven fabric or nonwoven composite material comprising the nonwoven fabric for shielding and absorbing electromagnetic waves, manufactured by using a carbon fiber plated with metal (copper and nickel) produced in an electroless or electrolysis continuous process. The nonwoven fabric of the present invention is thinner and stronger than the conventional art, and has an advantage of being capable of controlling conductivity by controlling only the content of the carbon fiber plated with metal, without need for further addition of conductive powder.
