The influence of the stitching on the fatigue life and on the residual post-fatigue quasi-static properties in two principal direction is investigated. The fatigue behavior of both composites is represented by Wöhler-like diagrams. The damage imparted during fatigue is studied by X-ray analyses. The present work aims to provide a contribution to understanding of tensile fatigue and post-fatigue behavior of a structurally stitched multi-ply carbon composite. To assess the influence of the structural stitching on the mechanical response of the stitched composite the experimental data are compared to the ones of the unstitched carbon composite counterpart. The term 'structural' means that the stitching yarn does not only consolidate the plies (as the non-structural one does) but forms also a through the thickness reinforcement. The quasi-static mechanical response of the considered stitched carbon composite, produced in a different batch, were experimentally investigated in [12].The first part of the paper presents the characteristics of the two composites and the description of the experimental techniques applied. In the second part, the tensile-tensile fatigue life is presented and compared by Wöhler-like diagrams. Pictures obtained by X-ray device are used to investigate the damage patterns produced during fatigue after different number of cycles for a stress amplitude. The last part of the paper is dedicated to the post-fatigue residual mechanical properties of composites undergone different number of cycles. During the post-fatigue quasi-static tensile tests, the techniques described in detail in [13] (acoustic emission registrations and optic full-field surface strain measurements) were used to investigate the damage onset and development. MATERIALSThe stitched and unstitched preforms (see Figure 1 and Figure 2) are laminated using two Seartex / 23Each NCF has a polyester sewing thread (8.3 tex, 2.6 x 5 mm tricot + chain knitting pattern, 6 g/m 2 )that knits together the carbon plies. The fabrics are stacked to form a symmetric laminate [45/-45/0/90/45/-45] S and has a total thickness of about 4.2 mm before impregnation. 90º direction corresponds to the non-structural sewi...

The fatigue of carbon fibre reinforced plastics - A review

“…There are two main types of 3D woven composites: interlock fabric, where the z-binder is interlaced with the in-plane yarns, and orthogonal fabric, where the z-binder holds in place the entire stack of 2D fabrics, thus avoiding crimp and maximising the in-plane stiffness [139]. Carvelli et al [147] showed that there is a dependency of these composites on the loading direction (when comparing 2D and 3D wovens) [0, 90] s orthogonal CFRP in both warp and weft directions and tested in (T-T) fatigue. The fatigue performance of the 2D samples were in between weft (lower) and warp (higher), although the difference was marginal, especially when considering the propensity for scatter when it comes to fatigue of CFRP.…”

Effects of Stitching on Damage Development for Non-crimp Fabric Composites based on Multi-scale Analytical Method

“…The stiffness and strength of laminates loaded in quasi-static tension can be unaffected, increase or more common reduced by stitching [11,12]. The characteristics of fatigue and post-fatigue behavior have been investigated [13], and the impact and post-impact properties for NCF composites have been estimated [14].…”
