Ship fitting sandwich panel Metawell® Aluflex

aluminum

Metawell® Aluflex is a material with rigidity levels that depend strongly on direction. The corrugated sheet is bonded with only one aluminium cover sheet. This structure enables easy 2D-forming and provides a high rigidity to curved lightweight construction elements (e. g. curved ceilings). Forming parallel to the corrugation Thanks to its special structure Metawell® Aluflex can be very easily transformed around the axis parallel to the corrugation tops, with smaller bending radii (e.g. for Metawell® Aluflex 05-02 / H4.7 smaller than 200 mm) even plastically. The bending parameters have to be determined case-wise to make sure that both bending radii and bending angle can be reproduced. In order to compensate the spring-back effect of the material, the´over-bending‘ is very important. The rigidity around this bending axis is relatively small. It may be necessary to additionally stiffen the element e. g. by gluing a metal sheet or other surface material to the corrugation in order to obtain a two-dimensionally formed „panel“. With this bending technique radii of 30 mm and more can easily be realized with Metawell® Aluflex 05-02 / H4.7.
