Abstract
Provided are stiffened stringer panels with integrated indexing stacks. An example composite panel comprises a skin member having an inner surface. An index for positioning a support tool comprises a first set and second set of layered laminate stacks coupled to the inner surface such that a channel is formed between the first and second set of layered laminate stacks. The first and second set of layered laminate stacks is configured to cradle a support tool in the channel to automatically align the support tool relative to the panel. A stringer may include a cap portion that extends from the first set to the second set of layered laminate stacks to form flange portions on the inner surface of the skin member. The index and the skin member may be co-cured or co-bonded.
