A composite hat stringer for stiffening a panel, comprising:
- a plurality of composite fabric plies arranged to form a cap, a pair of flanges and a pair of webs respectively connecting the cap with the pair of flanges;
- and
- at least one composite tape ply within the cap.
A stiffened composite panel assembly, comprising:
- a composite panel formed of multiple plies of composite tape, the composite panel including a base charge extending in a spanwise direction of the composite panel;
- and
- a composite hat stringer joined to the base charge and extending in the spanwise direction of the composite panel, the composite hat stringer being formed of laminated plies of composite fabric and including at least one composite tape ply.
A method of making a composite hat stringer, comprising:
- assembling a composite charge, including laying up a stack of composite fabric plies and interleafing at least one composite tape ply within the stack of composite fabric plies;
- and
- forming the composite charge into a hat shaped cross section having a cap, wherein the at least one composite tape ply is located within the cap.
