Abstract
A self-sealing bladder may automatically seal a puncture wound formed in a bladder wall thereof, such as due to being perforated by a projectile. Self-sealing bladders may be used in containers, such as fuel tanks, in order to prevent loss of fuel or other fluid from the container. Self-sealing bladders may contain a sealant material contained within one or more localized reservoirs formed within the bladder wall, the sealant material being pressurized within the bladder wall such that a localized reduction in pressure due to a perforation in the bladder wall causes the sealant material to migrate to the perforated site, whereupon the sealant material hardens, thereby sealing the wound. The localized reservoirs may include one or more channels and/or connecting layers extending therefrom and in fluid communication therewith, to facilitate migration of the sealant material away from the localized reservoirs and towards the perforated portion of the bladder wall.
