Step change in the weight-performance of forcible entry materials

Current materials to resist forcible entry or impacts tend to rely on increasing mass to increase resistance, this leads to limiting trade-offs as the weight of panels increase significantly and the corresponding issues.

This new material concept dubbed Proteus after the shape-shifting Greek god, in addition to acting as a hard surface that resists external pressure, the material turns the force of the drill or cutting mechanism back on itself, as the ceramic spheres create vibrations that disrupt the external force. These vibrations created can destroy the cutting blade through the aggressive movements, or widen a waterjet and thus depower.

The material has a further defence mechanism, as any attempt to cut the material breaks the ceramic spheres into smaller fragments which harden as the speed of the cutting tool is increased acting like
