3D woven textile reinforced composites allow the optimisation and tailoring of specific material properties into the final component that can provide a reduction in manufacturing cost. This paper investigates the damage imparted to 3D orthogonal woven fabric composite by drop weight impact and compression after impact (CAI) testing. Furthermore, specimens are analysed using computed tomography (CT) and through transmission ultrasonic inspection to observe how an impact event affects the structural integrity of the 3D woven composite. The 3D multi-layer reinforcements were manufactured on a textile loom with few mechanical modifications to produce preforms with fibres orientated in the warp, weft and through-the-thickness (TTT) directions. Orthogonal structures represent one of the more straightforward structures in terms of tow path complexity, yet also provide a structure where the advantages of low crimp tows bound together by a binder tow, result in a composite with high performance and reduced sensitivity to interlaminar shear.
