  A new kind of composite were manufactured by densification of co-crumpled
aluminium and tantalum thin foils using close die compression. It was shown by
optical micrography that its microstructure is highly interlocked. The
morphology was analysed quantitatively in terms of the following three
parameters: the area of the foil interface per unit volume, the interface
tortuosity, and a characteristic of the local orientation of the foil surface.
Based on these parameters, co-crumpled material studied has been compared with
conventional laminates. A fractal nature of its self-similar structure was
revealed.
