Testing of elastomers using new non-destructive techniques

A survey on ultrasound techniques, optical techniques, thermography, microw ave and x-ray techniques and one-side access nuclear magnetic resonance is given with respect to applications on non destructive testing of elastomers . The applications are detection of coating delamination, imaging of the in ternal microstructure of complicated shaped objects and characterisation of ageing, hardness and moisture content of materials. One-side access nuclea r magnetic resonance allows a detection depth of up to 30 mm on large test objects.
