Lubricant reservoir system

A fastener element extending in a longitudinal direction and in a transverse direction, the fastener element assembled to a machine part in an arrangement which transmits a load to the machine part, the fastener element being configured to be fixed at one axial end region of a longitudinal extension of the fastener element with the machine part and comprises a load area at a remote axial end region of the longitudinal extension of the fastener element in a load area, the remote axial end region being remote from the machine part, wherein the fastener element comprises a plurality of base parts extending in the longitudinal direction, the longitudinal extension is segmented into a first extension and a second extension,

• wherein adjacent base parts of the plurality of base parts are connected to each other by corrugations,
• wherein the fastener element is made of a composite material comprising continuous reinforcement fibers, the continuous reinforcement fibers are oriented having at least a portion of the continuous reinforcement fibers in a parallel arrangement, orienting extending from the machine part to the remote axial end region,
• wherein the corrugations have a substantially constant height along the first extension in the longitudinal direction of the fastener element, which the first extension extends from the machine part to a transition region, the second extension adjoins the first extension, the second extension extends from the transition region to the remote axial end region,
• wherein the load area comprises a plurality of connection holes, wherein each connection hole is arranged in a section of the plurality of base parts located along the second extension of the fastener element, and
• wherein along the second extension, the corrugations have a height that reduces from the transition region to a level of the portion of each of the plurality of base parts located along the second extension, and becomes zero at a final section of the fastener element in the remote axial end region.
