Abstract: A composite manufacture assembly is disclosed including a pair of closed mould tools for pressing a composite laminate panel therebetween, the closed mould tools having opposing inner surfaces that define an inner cavity that decreases in height along a span of the inner cavity in accordance with a curved rational function, the decrease in height corresponding to a designed thickness of the composite panel. The composite laminate panel including a stack of fibre-reinforced composite plies; a plurality of sets of ply drops spaced along a span of the composite laminate panel at which a corresponding set of plies terminate such that the thickness of the composite laminate panel varies along the span in accordance with the position and thickness of the sets of ply drops, each set of ply drops comprising one or more ply drops.

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