Abstract

Composite beam with integrated rupture initiator and aircraft fuselage including such beams. A composite beam ( 18 ) comprises a web ( 20 ) with a sinusoidal-shaped section and a bottom flange ( 22 ). The web ( 20 ) comprises a stack of at least one central layer of single-directional carbon fibers oriented along the depth of the beam, and aramide fiber and carbon fiber fabrics. The lower part of the beam ( 18 ) is designed so that rupture is initiated in it if the aircraft in which the beam is installed crashes. This is achieved by gluing the bottom flange ( 22 ) on the sides of the web ( 20 ), the bottom edge of each layer of single-directional carbon fibers is setback from the corresponding edges of the fabrics and saw-tooth cut-outs are formed in this bottom edge
