DexMat Carbon Nanotube Film: Will it Tear?

The films and yarns manufactured by DexMat are made from well-aligned carbon nanotubes; they are resistant to breaking or tearing across the direction of that alignment.

However, when working with these materials it is helpful to keep in mind that their toughness is much lower when the aligned layers are pulled apart. As this video demonstrates, it is difficult to cut or tear our carbon nanotube film “crosswise”, but the same film can easily be torn into strips “lengthwise”. The same is true for cutting with a scissors or razor.
