Abstract
THIS SBIR PROJECT ATTEMPTS TO DEMONSTRATE GAS TIGHT SEAMS IN CHEMICAL/BIOLOGICAL PROTECTIVE FABRICS SUCH AS TEDLAR, URATHAN, AND CHLOROPRENE. SEAM SEALING TECHNIQUES FOR EVALUATION INCLUDE ULTRASONICS, CEMENTS, AND DIELECTRIC, HEATED BAR, AND HOT AIR WELDING. HEAT SEALED SEAMS IN A SHEAR TYPE CONFIGURATION AND/OR A COMBINATION OF SEWING AND HEAT SEALED STRAPPING WILL BE INVESTIGATED. ALL CANDIDATE SEAMS WILL BE TESTED FOR LIQUID PENETRATION USING AN ASTM F903 PENETRATION CELL. TEST PILLOWS WILL BE MADE FOR THE MOST PROMISING CANDIDATES FOR EVALUATION USING A POSITIVE PRESSURE AIR TEST WITH A MAGNEHELIC GAUGE. ALL PERTINENT RESULTS AND DATA WILL BE SUMMARIZED IN A CLOSING REPORT.
