Abstract: Composite panels that include a metal skeleton of two superposed metal plates or sheets having groups of protruding bridge-shaped elements that extend into the interspace between the plates or sheets and overlap in a manner to form one or more elongated cage-like columns; a coherent matrix material made of a flowable or pourable mineral and/or organic matrix precursor is provided to substantially fill the interspace to form a substantially rigid compound structure of the panel constituents due to the plate-interlocking function of the cage-like columns. The panels can be flat or curved and are suitable as structural materials, notably as load supporting walls for buildings. Methods for producing such composite panels in a batchwise or continuous operation are disclosed.
