Abstract
The presently disclosed device provides a method and means for ensuring that containers of all types and sizes are vented or purged to atmospheric or environmental conditions upon the interior or exterior of the container reaching a critical temperature pressure, or humidity. Specifically, the presently disclosed invention integrates shape memory polymer (SMP) based, thermally activated fasteners into the venting systems. The result is a venting system that increases munitions safety without compromising the venting effectiveness, structural integrity, or the required bullet/fragment impact resistance requirements of the system.
Claims17
A venting system comprising:
- a container having an opening, and a first plurality of active material fasteners surrounding the opening;
- and
- a vent cover comprising a frame and a second plurality of active material fasteners disposed on at least one side of the frame,
- wherein the vent cover is configured to be attached to the container by engagement of the said first plurality of active material fasteners with said second plurality of active material fasteners, and
- wherein internal pressure in the container is configured to fully separate the vent cover from the opening of the container after activation of said first plurality of active material fasteners and said second plurality of active material fasteners.
A method comprising:
- providing a venting system comprising:
- a container having an opening and a first plurality of active material fasteners surrounding the opening;
- a vent cover attached over the opening of the container by engagement of the first plurality of active material fasteners and the second plurality of active material fasteners;
- and
- activating both said first plurality of active material fasteners and said second plurality of active material fasteners;
- and
- detaching the vent cover from the container after activation of said first plurality of active material fasteners and said second plurality of active material fasteners, wherein the vent cover fully separates from the opening of the container due to internal pressure in the container.
