Claims
- 1. A composite material for EMI/EMP hardening protection, comprising:
- a preselected 0.01-10 weight percent of non-conducting, non-corrosive matrix material selected from a group of insulating polymers consisting of a PEEK polymer, a polycarbonate polymer and a polycarbonate polymer with an inherently conductive polypyrrola polymer plastic additive;
- 0-10 weight percent of conducting Nickel-flake particles, embedded in said non-conducting matrix;
- 5-15 weight percent of non-corrosive semi-conducting oxide particles selected from the group consisting of Indium Tin Oxide, Indium Oxide and Tin Oxide, embedded in said non-conducting matrix and acting in cooperation with said conducting particles in such a way that galvanic potential is lowered;
- said preselected weight percent of matrix material comprising the remainder of said composite material.
- 2. A composite material according to claim 1 wherein said semi-conducting particles are Indium Tin Oxide powder.
- 3. A composite material according to claim 2 wherein said matrix material is a PEEK polymer.
- 4. A composite material according to claim 2 wherein said matrix material is a polycarbonate polymer.
- 5. A composite material according to claim 2 wherein said matrix material is a polycarbonate polymer with an inherently conductive polypyrrole polymer plastic additive.
- 6. A composite material according to claim 3 comprising 15 w/% Indium Tin Oxide, 10 w/% Nickel flake and 75 w/% PEEK polymer.
- 7. A composite material according to claim 4 comprising 15 w/% Indium Tin Oxide, 10 w/% Nickel flake and 75 w/% polycarbonate polymer.
- 8. A composite material according to claim 5 comprising 15 w/% Indium Tin Oxide, 10 w/% Nickel flake and 73 w/% polycarbonate with 2 w/% inherently conductive polypyrrole polymer.
