Through non-destructive analysis, the ESRF and ELETTRA facilities can investigate the changes that composites materials undergo and correlate a material’s micro- and nanostructure with its properties.
Using synchrotron light Photoemission quantitative and qualitative chemical characterization of morphologically complex materials studies on chemical reactions and mass transport processes can be performed, in order to understand changes in the composition, morphology and electronic properties of materials.
As an example, it is possible to study the internal failure mechanisms of composites using 3D imaging (X-ray tomography) and assess the position, size and orientation of particles in carbon nanotube fibres using a combination of wide-angle X-ray scattering and fluorescence data. Moreover the use of microfocus X-ray beams is helpful to characterise nanostructure of fibre-reinforced composites and high performance fibres or analyse the open porosity in foams and residual porosity in sintered objects and the physico-chemical properties.
Using X-Ray Diffraction, residual stress and texture analysis, phase identification and structural studies and kinetic studies could be performed. Systems that can be investigated vary from organic and inorganic thin films to thermally and/or mechanically modified surfaces of mechanic components. Even polymers, catalysts and highly disordered materials in the form of films, powders, fibers can be studied as well as residual strains in the metal and ceramic phases separately and simultaneously in metal matrix composites.
Complementary to static structure determination, the two facilities allow the study of composites materials during their synthesis or under realistic working conditions, which helps manufacturers to identify and exploit material’s properties in new ways. Thanks to the high spatial resolution x-ray tridimensional characterisations, researchers can investigate multiphase materials and study the nanoscale structure of composite nanosystems. Parameters as  averaged particle sizes, shapes and distributions, the materials’ porosity and degree of crystallinity as well as electron density maps with nanometer precision can be obtained.

This workshop presents a unique opportunity to get hands-on practical experience of the various X-ray techniques available at the ESRF and ELETTRA that are offered to industrial customers for proprietary experiments with a fast and flexible access and a modular, personalized service under the close guidance and support of the scientists.
