Terahertz for Ceramic and Composites

Terahertz radiation is ideal for analysis of advanced composites and ceramic materials and is capable of providing insight into the structure of optically and infra-red opaque ceramic materials. Due to the properties of Terahertz radiation 3D imaging of flaws, defects and buried structures is possible. Terahertz measurements are non-contact and non-destructive, plus requires no liquid medium, as well as being insensitive to ambient temperatures.

Applications include

• Aircraft ceramics and composites for stress cracks and defects and voids
• Imaging of coating structures on refractory ceramics
• Investigation of ceramic joints/welds
• Investigation of vehicle ceramic catalysts for defects and carbon deposits
