Abstract:
Process for assembly of a flexible panel on an open, elastically deformable structure that is stiffer than the panel, said process comprising a pre-assembly step of bonding the panel onto the structure, followed by an attachment step of attaching the panel onto the structure by means of mechanical attachment devices, wherein the pre-assembly is done by cold gluing;wherein the cold gluing is done by assembling the structure onto a rigid chassis, by positioning the panel on the structure with insertion of glue and pressing the panel into contact with the structure; wherein the structure comprises a perforated framework, in which the panel is locally pressed into contact with this framework, mainly in unperforated parts of the framework; wherein the perforated framework comprises essentially C-shaped ribs and devices forming stiffeners connecting these ribs together, in which the panel is pressed into contact with these devices over most of their length, and the panel is also pressed into contact with these ribs at local positions between devices forming stiffeners; wherein the radius of curvature of the ribs is variable, with a minimum value in the central region, the panel is also pressed into contact with the central regions of the ribs over most of the length of the perforated framework; wherein the panel is progressively pressed into contact with the perforated framework, firstly by bringing the panels into contact with the said central regions of the ribs and then progressively working towards the rib end regions.
