【 摘 要 】

3-Dimensional fabrics have been developed in order to remedy the damage through-the-thickness of the laminate. An alternative to the multi-layered preforming is to use structures reinforced through-the-thickness in order to manufacture thicker and more complex pieces. Currently, the tufting technology is getting more interest due to its simplest and efficient process where it involves the insertion of binder threads via a single needle through the fabric. This technique of reinforcement through-the-thickness requires only one access to the preform which makes it suitable for three-dimensional shapes. This study aims to improve the understanding of the mechanical behaviour of tufted preforms where an experimental investigation was performed in order to study the in-plane shear of tufted structures. The effect of the tufting process on the mechanical performance of dry fabrics is also highlighted in the present work.
