Abstract: A seal arrangement is provided for sealing an exposed edge of a composite laminate part having a fay surface configured to be joined to a structure. The seal arrangement includes a precured edge seal covering the exposed edge and a cover covering the edge seal. A seal bead located within a recess in the fay surface of the part forms a seal between the part and the structure.

Abstract: Disclosed herein are methods and apparatuses for curing a polymerizable material capable of cure through a redox reaction by electrically contacting the polymerizable material with an anode and a cathode to create a voltage bias that promotes curing of the polymerizable material.

Abstract: A high-volume low-pressure end effector is presented. The high-volume low-pressure end effector comprises a connection arm and a spray head. The connection arm comprises a housing with flexible conduits running through the housing. The spray head has integral channels configured to receive air and a fluid from the flexible conduits and deliver the air and the fluid to a number of outlets.

Abstract: An adhesion promoter composition is disclosed. The adhesion promoter composition includes a first reactive silane compound and a second reactive silane compound, where the second reactive silane is different from the first. The adhesion promoter composition also includes one or more organic solvents and an organic base. A method for applying the adhesion promoter composition is also disclosed.

Abstract: A method may be present for securing a strip in a structure. A first surface of the strip may be masked with a first tape. A surface of the structure may be masked with a second tape, the surface of the structure defining a desired shape. A sealant may be applied in a groove in the structure. The strip may be positioned in the surface such that a second surface of the strip contacts the sealant; and a caul plate may be pressed against the first surface of the strip, the caul plate including a set of ribs that contact the fairing strip, and the plurality of ribs defining a shape that substantially matches the shape of the surface of the structure. Pressing the caul plate against the first surface of the strip may cause sealant to pass between the set of ribs onto the tapes.
