Summary:COMPOSITE HAT STIFFENER A hat stiffener (304) disclosed herein that includes a web portion having locally optimized slopes. The hat stiffener (304) may include a web portion having a relatively small slope optimized to handle a sheer force. The hat stiffener (304) may further include a web portion having a relatively large slope optimized to handle a pull-off or interface force. The hat stiffener (304) may include a hat cap (306) having variable widths along the length of the hat stiffener (304). The hat stiffener (304) may further include a transitional web portion to transition from a web portion having a relatively large slope to a web portion having a relatively smaller slope. The concepts disclosed herein allow for the generation of a one-piece hat stiffener (304), which can be locally optimized to improve structural capability and efficiency for different loading applications. caI cn C131 - co ce)
