Metallic-Ceramic Multi-Material Composite for Protection from Forcible EntryThursday (29.09.2016) 09:45 - 10:00 Part of:
Metallic-ceramic multi-material composite panels were produced to protect critical facilities from forcible entry, with tools such as angle grinders and power drills. Recent advances in portable cutting tools created a vulnerability for high-security infrastructure. Therefore, the University of Surrey, the Home Office in the UK and Fraunhofer Institute for Machine Tools and Forming Technology IWU developed and manufactured metallic-ceramic composite. The prototype panels defeated common cutting and forcible entry tools in the independent tests conducted in the Centre for Applied Science and Technology of the Home Office in the UK. The manufactured multi-material composite showcased how to combine metallic foams, ceramic inclusions, various meshes and steel plates to achieve desired response to loadings from multiple cutting and drilling tools. Secure doors and partitions for governmental facilities are obvious target application, with exploratory potential for the use in light-weight military installations in the future. The design may also inspire other industrial applications that require multi-physical functionality. Future work is needed on automation of the production to enable mass manufacturing and to reduce the cost of the hierarchical material.
