INTRODUCTION Proportions of composites materials for aeronautic applications have dramatically increased over the last decades because of their inherent properties combining high mechanical properties with low mass. However, the major concern of the traditional 2D composites is the reduction of properties due to delamination between plies because of weak through-the-thickness properties. Three dimensional woven give the possibility to add a 3 rd direction of reinforcement with the addition of yarns interlacing through the thickness. The main benefit of that additional direction of reinforcement is a better damage tolerance due to impact where delamination is the key failure mode. With the addition of that 3 rd direction of reinforcement, possible combination of interlacement become extremely numerous. Different patterns commonly observed fall into 2 main categories: The orthogonal 3D woven, which is made of three different type of yarns, the
