POROUS MATERIALS
GROUP |
The Porous Materials Group conducts research on the manufacture and characterisation of particulate and porous materials. Our current focus is to develop the patented Lost Carbonate Sintering (LCS) process for manufacturing porous metals, to study the mechanical, thermal, electrical, acoustic and biological properties of porous metals and metal matrix syntactic foams, and to explore their feasibility for applications in energy, automotive, defence, aerospace, building and biomedical industries.
