Abstract: Fasteners pre-dosed with a curable sealant material encased within an at least partially-cured rupturable protective shell and methods are disclosed for the application of a selected curable sealant material dose to an aircraft assembly that is delivered simultaneously to an aircraft assembly location during fastener installation.

Abstract: An energy-absorbing bulkhead apparatus includes high-strength roll formed tubular bars, and a bar-supporting sheet to distribute stress from product shifting in large shipping containers during transport. Parts are re-useable and can be quickly installed into the shipping container at selected locations such as near the container's doors. The bars can be swept and/or have deformed/configured ends shaped to engage channel features in side walls of the large shipping container. The bars may define spaced tubes and a tie rod for added strength. For example, the bars can be steel having 120 KSI to 220 KSI tensile strength, and have a cross-section 2-3 inches in depth and 4-6 inches in height, a length of 94 long, and a longitudinal sweep of 6 inches curvature. A flexitank can be positioned in the shipping container and supported by a combination of the bulkhead.
