Abstract

Stiffener chamfering was developed to eliminate wrinkles of composite laminate and buckling of the fiber during co-bonding of stiffened composites.The evolution pattern of wrinkles and buckling under different chamfering angle were studied by section metallographic microscopic analysis.The influence of chamfering angle on stiffened panel rigidity was analyzed by building a cantilever beam model.Results revealed that wrinkles of composite laminate was eliminated after chamfering of stiffener,and as the chamfering angle decreases,the buckling of the fiber decreased gradually,the rigidity of the stiffened panel increased first and then decreased.Thus,the 30° chamfering of the stiffener was appropriate during co-bonding of stiffened composites.
