Injectable cap
The present invention proposes a cap (100) for forming a sealed cavity (12) around one end of a fastener (2-4) to thereby contain out-gassing and sparking events in the event of a lightning strike to the fastener (2-4). The invention also proposes a joint comprising such a cap (100), and a kit of pa...

| description | The present invention proposes a cap (100) for forming a sealed cavity (12) around one end of a fastener (2-4) to thereby contain out-gassing and sparking events in the event of a lightning strike to the fastener (2-4). The invention also proposes a joint comprising such a cap (100), and a kit of parts and method for installing such a cap (100). A cap (100) according to the invention comprises: an inner cap member (10) having an annular base (11) terminating at an edge (18) which surrounds an opening into an air cavity (12) for enclosing the one end of a fastener (2-4); and an outer cap member (20) having an annular skirt or flange (40) which extends radially outwardly away from the annular base (11), the annular skirt or flange (40) and annular base (11) between them defining an annular sealing cavity (34a-c). The cap (100) also comprises a sealing material inlet (44) comprising an opening (22) in the outer cap member (20) that is in fluid communication with the annular sealing cavity (34a-c), the opening (22) being arranged to interconnect with a sealing material injection device (80) to provide a flow of curable sealing material (81) from the sealing material inlet (44) into the annular sealing cavity (34a-c). The outer cap member (20) has an inner surface formed with a first locking feature (95,96), and the inner cap member (10) has an outer surface formed with a second locking feature (97) which forms a snap-fit joint with the first locking feature (95,96). |
