X-ray tomography is a non-destructive technique which allows reconstruction of the internal geometry of opaque and massive materials in three dimensions (3D). This chapter first discusses the capabilities of this technique in the field of the mechanics of composite reinforcements. It then describes methods of analysing reconstructed data at different characteristic length scales. The chapter also includes an example of the use of such analyses to develop a numerical model of the mechanical behaviour of a woven composite reinforcement.
