Micro-CT in Composites

CFRP Bend Test

X-ray micro-computed tomography (μCT) is
an advanced technique that gives you 3D insights into samples of any material, in any shape or size with little to no sample preparation.

The Bruker SkyScan range includes scanners for every facility – from desktop, automated systems that scan at the press of a button to floor-standing, multi-scale micro- and nano-CT instruments.

Generate 3D images with resolutions down to < 1 µm


Micro-CT (also referred to as XRM or X-Ray Microscopy) is used in areas such as:

3D internal imaging

  • Resolve fine structures with voxel sizes down to 0.35 μm
  • Completely non-destructive
  • Take virtual cuts, slices and even flights through your object

Analyse structure and composition

  • Microstructural composition
  • Architecture
  • Porosity
  • Quantify defects
  • Fibre thickness and orientation
