Composite Characterisation facilities

X-radiography

XrayDigital X-ray inspection can be performed using our stand alone x-ray system. This equipment allows fast and easy x-ray inspection of parts. If required, we can treat our composite parts with a contrast media for better defect detection.

  • Energy range: 10 kV – 100 kV
  • Tube Current: 180 mA – 1.0 mA
  • Resolution: 5-45 µm
  • Maximum sample size 350mm x 430 mm
  • Chamber height 410mm

Ultrasonic inspection

USWe inspect manufactured and tested panels and parts using our Ultrasonic C-scan. The large tank allows even large structures to be inspected. Curved specimens can be analysed, using a device to ensure that the ultrasonic probe is aligned normal to the test surface throughout the scan. In addition to the pulse-echo set-up, we can also test in through transmission mode. A portable, hand-held ultrasonic inspection device (DolphiCam) is also available which does not require the specimen to be immersed in water. This allows inspection of composite parts  of up to 8mm thickness in the field.

  • Immersion tank: 1700 x 1300 x 500 mm
  • Max. scanning speed: 500mm/s
  • Min. acquisition index: 0.1mm
  • Probes 1MHz – 15MHz

Optical microscopy

microscopyWe do have a dedicated materials lab for micrography and fractography inspection of composite materials. Our Zeiss optical microscope is equipped with a motorised stage. This allows automated imaging of large areas at high magnification, including image stitching.
