The present paper focuses on in-situ multi-axial testing of three-dimensional (3D) woven organic matrix composites for aeroengine applications. Damage onset is characterised by X-ray µ-Computed Tomography (µCT) based in-situ tests, supported by Acoustic Emission (AE) analysis and by Finite Element (FE) simulations. The synergy between these techniques allows having knowledge of the solicitation at which damage onsets and defines the first points necessary for the construction of a damage onset surface at the sample scale.
