摘要： Method for arranging at least one blade building preform element (7) in a blade mold (8) for further processing, comprising the steps:
a) placing the at least one preform element (7) on a mold surface of the blade mold (8),
b) placing at least one further preform element (26) and/or at least one blade component and/or at least one manufacturing tool (10) on the mold surface and/or on the at least one preform element (7) by moving it in a moving direction along a moving path (12), and
c) bending at least one part of at least one bending section (9) of the at least one preform element (7) such that the at least one bending section (9) at least partially overlaps the at least one further preform element (26) and/or the at least one blade component and/or at least one manufacturing tool (10) such that the at least one bending section (9) blocks a reverse movement of the at least one further preform element (26) and/or the at least one blade component and/or at least one manufacturing tool (10) in the reverse direction along the moving path (12).

摘要： A composite laminate heating tool broadly comprising a substructure, a facesheet, and number of expansion joints. The substructure supports the facesheet but does not need to have the same or a similar CTE as the facesheet because the facesheet is free to expand relative to the substructure. The expansion joints provide an interface between the facesheet and the substructure so that the facesheet can thermally expand relative to the substructure while being fully supported by the substructure. Each expansion joint includes a guide attached to the substructure and a support member translatable relative to the guide and aligned radially from a centroid or center of expansion of the facesheet so as to have a single degree of freedom.

摘要： The structural element for aircrafts, comprises a web (1), a foot (2) and a curved portion (3) defined between the web (1) and the foot (2), the web (1), the foot (2) and the curved portion (3) comprising at least first layers (4) with fibers defining a first orientation; and second layers (5) with fibers defining a second orientation, the first layers (4) comprising a plurality of gaps (7) at the foot (2) and/or the curved portion (3).
The method comprises stacking a plurality of first and second layers (4, 5); cutting a plurality of gaps (7) in the first layers (4) in a zone that will form the foot (2) and/or the curved portion (3); cutting a contour of the stacked first and second layers (4, 5); and shaping the stacked layers (4, 5).
