    • PROBLEM TO BE SOLVED: To provide a composite structural member with fiber reinforcement.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.
    • 要解决的问题:提供具有纤维增强的复合结构构件。 解决方案:本发明涉及具有纤维增强件的复合结构件及其在生产用于飞机的翼箱中的应用。 更具体地说,本发明涉及一种具有纤维增强材料的复合结构件(230),其包括在包括0°,90°和+/-θ的方向上相对于构件的纵向方向(2)定向的多个层; 这些取向之一中的层之间的相对比例沿着该构件的横向方向(3)是可变的,以便根据沿该横向轴线(3)的规定的机械应力分布来空间调整构件的刚性。 因此,构件的刚性局部地适应于应力系统,以便在构件的整个体积上消散力通量。 版权所有(C)2012,JPO&INPIT
