- Cutting resistance is essential in protective structures, such as security doors and for workers safety in industrial environments with robotic cutting tools. Here, we created the first manufactured non-cuttable material with a hierarchical cellular, metallic structure with embedded ceramic segments. The segments resonate with the cuttings tools, the resulting vibrations with the associated grinding action of particulate matter following their fragmentation destroy the cutting discs and drill-bits. The material was rated as the only manufactured, non-cuttable material by the Home Office (Jessica.Sorrell@homeoffice.gsi.gov.uk). This work featured in Editor's pick of Science magazine and national and international press and TV.
