Composite stringer packages and systems and methods for constructing composite stringer packages

A method for constructing a composite stringer package, the method comprising steps of:

• positioning a deformable membrane on a tray;
• assembling the composite stringer package that comprises a hat-shaped cross-section;
• positioning a lid in a closed state relative to the tray to form a sealed chamber;
• with the lid in the closed state, applying vacuum to the sealed chamber;
• and
• compacting, by application of the vacuum, the composite stringer package between the deformable membrane and the lid.

A composite stringer package comprising:

• a composite charge that is positioned in a receptacle of a tray such that a deformable membrane that lines the tray is situated between the composite charge and the tray;
• a bladder that is positioned in the receptacle such that the composite charge is situated between the deformable membrane and the bladder,
• wherein:
• the composite charge and the bladder are enclosed within a sealed chamber that is formed by a lid and the tray;
• and
• the composite charge and the bladder are compacted between the deformable membrane and the lid to form a consolidated composite stringer package by applying vacuum in the sealed chamber through the deformable membrane.
