<P>PROBLEM TO BE SOLVED: To provide a composite structural member with fiber reinforcement. <P>SOLUTION: The invention relates to the composite structural member with fiber reinforcement and its application in the production of a wing box for aircraft. More specifically, it relates to a composite structural member (230) with fiber reinforcement comprising a plurality of layers oriented relative to a longitudinal direction (2) of the member in directions including 0°, 90° and +/-θ; the relative proportion of layers in one of these orientations being variable along a transverse direction (3) of the member so as to spatially adjust the rigidity of the member according to a defined distribution of mechanical stresses along this transverse axis (3). Thus the rigidity of the member is adapted locally to a stress system so as to dissipate the force flux over the entire volume of the member. <P>COPYRIGHT: (C)2012,JPO&INPIT |
