Methods for reworking structures and reworked cellular core panels, reworked structures comprising the reworked cellular core panels, and guides and cutting apparatuses for reworking cellular acoustic panels and reworking cellular acoustic and non-acoustic panels are disclosed.

Structural rework of cellular core panels

Methods for reworking structures and reworked cellular core panels, reworked structures comprising the reworked cellular core panels, and guides and cutting apparatuses for reworking cellular acoustic panels and reworking cellular non-acoustic panels are disclosed.

A tank and associated fabrication method are provided which may limit the damage otherwise occasioned by the impact of a ballistic projectile. The tank may include a wall assembly defined between outer and inner walls and a plurality of restraining elements that extend between the walls. The restraining elements may be formed to have a plurality of layers of material that form not only the restraining element, but also portions of the inner and/or outer walls. For example, the tank may include a plurality of cells positioned adjacent to one another with each cell forming portions of two adjacent restraining elements and portions of the inner and/or outer walls. A corresponding method for fabricating a tank including a wall assembly having a plurality of restraining elements is also provided.
