Abstract
In a structural member with large unidirectional rigidities unidirectional fiber bundles are completely embedded in shear resistant sheaths. The shear resistant sheaths are joined to a shear resistant torsion shell made up of skin layers by shear resistant vertical walls. A part of the vertical walls is shaped into stringers. Dividing layers (20) interrupting the passage of tension between adjacent unidirectional fiber bundles (30) are provided between the shear resistant sheaths (31) of the unidirectional fiber bundles (30).
