Abstract
CANS WILL BURST FROM OVER-PRESSURIZATION AS A RESULT OF THE AEROSOL CAN IS A CONSUMER CONVENIENCE ITEM USED FOR MANYYEARS. HOWEVER, SAFETY PROBLEMS HAVE EXISTED BECAUSE THE CANS WILL BURST FROM OVER-PRESSURIZATION AS A RESULT OF OVER-TEMPERATURE. THE PROBLEM IS MADE ACUTE BY THE INTRODUCTION OF FLAMMABLE PROPELLANTS AND SERIOUS CONCERNS EXIST FOR SAFE TRANSPORT OF THESE CANS IN AIRCRAFT CARGO COMPARTMENTS. THE INITIAL GOAL OF THIS PROPOSED PROJECT IS TO INCREASE THEWORKING PRESSURE FROM THE PRESENT MAXIMUM (DOT 2Q, 270PSI) TO 450 PSI AND TO PROVIDE OPTIONAL RIM VENTING. THIS APPROACH WILL REDUCE FIRE HAZARD AND OFFERS THE FURTHER OPPORTUNITY OF UTILIZING HIGHER PRESSURE NON-FLAMMABLE PROPELLANTS. DURING PHASE I, EFFORTS WILL BE FOCUSED ON THREE-PIECE CANS. LASER WELDING OF DOUBLE SEAMED ENDS WILL BE UTILIZED TO ACHIEVE HIGH STRENGTH END SEAMS. THIS TECHNOLOGY WILL BE COMPARED TO EXTRAPOLATION OF CONVENTIONALDOUBLE SEAM TECHNOLOGY TO OBTAIN SIMILAR HIGH BURST STRENGTHS. THE IMPROVED AEROSOL CAN WILL REDUCE FIRE HAZARDS IN THE NATION'S TRANSPORTATION SYSTEM AND IMPROVE SAFETY FOR THE CONSUMER MARKET BY REDUCING THE BURSTING PROPENSITY.
