The benefits

Non-destructive testing using terahertz measurement techniques

Composite­materials­such­as­glass-fiber­reinforced­or­carbon-fiber­reinforced­polymers­

(GFRP/CFRP) are being used increasingly as a result of their special properties. The testing

of these materials makes high demands on the selected test procedure. Using terahertz

measurement techniques, it is possible to test composite materials on the surface and in-

side. Variations in thickness, defects, cavities, inclusions and pores can be reliably and

clearly detected using this measurement technology.

Terahertz measurements are contact-free and do not require any additional coupling medium,

thus avoiding the not uncommon problem of residue removal. In contrast to contact-free

X-ray techniques, terahertz measurement techniques present no health risks..
