DISBOND RESISTANT COMPOSITE STIFFENER RUNOUT

摘要

PROBLEM TO BE SOLVED: To provide a disbond resistant composite stiffener runout.SOLUTION: Various aspects herein may be used independently or in combination. Aspects include a stiffener runout having rounded base flange corners. A recessed notch may be incorporated within a base flange to provide a flange termination point 206 that is forward of a web termination point 208, allowing a web to terminate prior to the base flange 108. The web may be trimmed from a full height to a reduced height at the web termination point. The base flange may be co-bonded to an underlying composite structure 104 via a scarf joint. Perimeter clamp radius fillers 112 may be used to concentrate a clamping force around the perimeter of the base flange.
