  • Method for bladder repair during composite part curing
    Patent number: 9925697
    Abstract: A system and method of a method of sealing a leak in an internal bladder within a hollow uncured composite part during cure thereof. The method may include placing a rescue bladder within the internal bladder and sealing an impermeable membrane and/or rigid forming tool to the rescue bladder, such that the uncured composite part is sealed within a chamber cooperatively formed by the impermeable membrane, the rigid forming tool, and the outer surface of the rescue bladder. A vent opening of the rescue bladder and/or a vent opening of the end fitting may remain located outward of the chamber. The method may also include curing the hollow uncured composite part, introducing a pressure differential causing the rescue bladder to inflate and press the internal bladder against an inner surface of the hollow uncured composite part.
