Abstract: A system to adjust extension lengths of slats of a work platform relative to a workpiece includes sensors to collect first data associated with a position of an outer surface of the workpiece at a height of the slats. The system includes actuators configured to extend or retract the slats. The system also includes a controller coupled to the sensors and to the actuators. The controller is configured to receive the first data and second data associated with rotation of the workpiece. The controller is configured to provide signals to the actuators of the work platform based on the first data and the second data. The signals cause the actuators to adjust or maintain extension lengths of the slats of the work platform to maintain separation distances between ends of the slats and the outer surface of the workpiece within a separation distance range as the workpiece rotates.

Abstract: A carrier film set configured to apply a number of stiffener assemblies to a layup mandrel, the carrier film set comprising: a number of alignment features configured to align the carrier film set relative to the layup mandrel; and a number of indexing features configured to index the number of stiffener assemblies onto the carrier film set.

Abstract: A method of fabricating a composite structure is presented. The method comprises laying up a plurality of composite plies over a layup mandrel; positioning a first caul plate and a second caul plate over the plurality of composite plies, leaving composite material exposed; removing at least part of the composite material exposed between the first caul plate and the second caul plate to separate a first composite section from a second composite section; curing the first composite section and the second composite section to form a first composite part and a second composite part; and removing the first composite part and the second composite part from the layup mandrel immediately following curing.
