Abstract

IN AN SBIR PHASE I CONTRACT WITH THE U.S. ARMY MISSILE COMMAND AT REDSTONE ARSENAL, AL., THE PEM RESEARCH CO. OF LARGO, FL., DEVELOPED PROCEDURES TO FABRICATE DIELECTRIC TEST SAMPLES WITH THERMOSETTING PLASTICS AS THE DIELECTRIC AS WELL AS ASSISTED THE PROJECT MANAGER IN ANALYSIS OF DIELECTRIC BREAKDOWN SAMPLES. IN THE PHASE II PROPOSAL PEM RESEARCH CO. PROPOSES TO SUPPLY THE PROGRAM MANAGER WITH DIELECTRIC SAMPLES HAVING ARTIFICIAL VOIDS AS WELL AS SAMPLES WHICH ARE FILLED WITH COMPOUNDS WHICH IN THE CERAMIC FORM ARE GOOD MICROWAVE DIELECTRICS. THE SCOPE OF TESTING PROPOSED BY PEM WILL CONSIST OF BOTH STATIC PULSE AND FAST RISE PULSE TESTING OF POLYMERS. PEM PROPOSES TO MAKE A FAST RISE PROTOTYPE GENERATOR TO PERFORM THESE TESTS. ANOTHER PHASE OF THE EXAMINATION WILL CONSIST OF AN EVALUATION OF THE MOST FEASIBLE METHODS OF ELECTRODING SAMPLES FOR ELECTRICAL TESTING. METALLIZING BY VACUUM PLATING AND ION IMPREGNATION AS WELL AS SILVER PAINTS WILL BE EXAMINED. TO DETERMINE THE MECHANICAL INTEGRITY OF THESE DIELECTRICS MECHANICAL PROPERTIES WILL BE EXAMINED. THE DIELECTRICS WILL BE USED IN STRUCTURAL APPLICATIONS THUS, IT IS RECOMMENDED THAT RESIN-FIBER COMPOSITES ALSO BE EXAMINED.
