Fibre analysis by X-ray tomography

Measure and visualise the 3D architecture of your fibrous materials, from micro to macro

Volume fraction, spatial orientation, distribution, fibre length and curvature, impregnation quality… We quantify the key parameters that govern the mechanical, thermal or biological performance of your materials.

Thanks to X-ray tomography, these measurements become accessible in 3D and under real conditions, allowing us to directly link microstructure and functional properties. Whether you want to optimise a process, guarantee the reliability of an aeronautical composite, control the filtration of a non-woven fabric or understand the mechanics of collagenous tissues, our services transform microstructure into usable data to innovate and secure your developments.

Key parameters for fibre characterisation

  • Fibre volume content: local/global volume fraction

  • 3D orientation: angular distribution, orientation tensor, anisotropy

  • Length/diameter/slenderness: short fibres, long fibres, strand

  • Waviness, curvature, interfibre contact

  • Spatial distribution: fibre-poor/loaded zones, process gradients

  • Fibre/matrix interfaces & impregnation: interfacial voids, wetting, adhesion

  • In situ evolution under tension, compression, and thermal stress: monitoring of the initiation/propagation of fibre breaks, decohesion, and delamination

Heritage (archaeology, conservation)

  • Non-destructive 3D reconstruction of fibre weaves, armatures and orientations, even on fragile or degraded parts

Organic fibers and fibrous tissues

Biological Tissues: cartilage, tendon, skin

  • Quantification of the 3D orientation and degree of alignment of collagen fibres
  • Measurement of the natural undulation of collagen fibres
  • 3D observation of collagen network remodeling during mechanical tests, analysis of rupture and structural laxity mechanisms

Cosmetics – hair & keratin fibres

  • Hair Strand: 3D geometry, curl/curvature, inter-fibre contacts, variations after treatments
  • Fibre: cuticle/cortex/melanin/possible medulla, variations after treatments (bleaching, heat)
  • Objective quantification, 3D visual aids for R&D and technical marketing

Why choose micro-CT for fibre analysis?

  • Non-destructive & representative 3D: no biased slices; entire volumes or multi-resolution regions of interest
  • Multi-scale down to nano-tomography: from cm to ~50 nm in synchrotron, to link architecture and performance
  • Real-time in situ: direct observation of orientation under load and damage mechanisms; reference data for modelling
  • Robust quantitative measurements: orientation tensor, length/diameter distributions, waviness/crimp, volume fraction, heterogeneity maps
  • AI & simulation compatibility: 3D datasets for training/validation, critical zone detection, process model calibration
