“…Also several authors [25][26][27][28][29][30][31][32] estimate the macro woven fabric composite behaviour as elastic. The behaviour could be written as follow, Equation 12-17: ( Then the analytic elastic properties of the macro scale behaviour of the woven fabric G1151/Resin Epoxy could be calculated and are listed in the…”

In this paper an experimental analysis of the failure of a single layer woven fabric composite 2.5 D G1151/ Resin Epoxy through a tensile tests at 0°, 45° and 90° is investigated. In addition a FE simulation of failure were elaborated through multiscale modeling method, micro then meso then macro scale. The microscale simulation was elaborated on ABAQUS standard simulation of a 3D unit cell of random fibers distribution of a single yarn. The meso scale simulation developed on MATLAB. The meso approach based to the extraction of the behavior of representative volume elementary (RVE) of the 2.5 D woven composite. The macroscale simulation was elaborated on ABAQUS standard simulation. With reference to the numerical and experimental study, the results shows a good agreement. The present investigation is an important preliminary study in process forming of single woven carbon 2.5 D composite.

“…In the laminate studied here, around 200 fibers can be found in a yarn and the detailed representation in a numerical model would lead to huge computation time. Some attempt was proposed by Döbrich et al [12]. They have derived the homogenized behavior of a composite with woven glass fabric, based on a numerical model where the fiberglasses were meshed.…”

The elastic orthotropic behavior of thin woven composites is studied combining a numerical and experimental strategy. For thin materials, in-plane properties are measured by classical tensile tests and digital image correlation. The out-of-plane properties are derived performing finite element simulations at the level of the internal structure of the laminate. Indeed, the glass fiber arrangement in the yarn and the weaving pattern are defined based on microtomography and SEM observations. So a representative unit cell is found. A statistical approach is further proposed to derive the behavior of the warp and fill yarns, since the fiber position may fluctuate between yarns. For the considered laminate, the matrix (resin and ceramic inclusion) behavior is unknown and difficult to measure. Therefore an inverse method is proposed. By comparing with measured in-plane elastic moduli, behaviors of the matrix, of yarns and of the laminate are defined. The present homogenization strategy is exemplified by laminates used in printed circuit boards for high frequency applications. This approach has also been applied to investigate the evolution of the elastic moduli of the laminate with temperature. Those information, usually not available in the literature, are important when dealing with reliability of printed circuit boards during thermal cycles.

“…However, the effect of internal defects on the strength was not included. Döbrich et al (2016) paid attention to a micro-scale character of a reinforcing textile in their study of a meso-scale RUC; this is not common due to higher computational efforts compared with multi-scale approaches. In this study, a digital element approach was used to model the textile structure with a near micro-scale resolution for the purpose of reinforcement analysis.…”

Composites reinforced with woven or braided textiles exhibit high structural stability and excellent damage tolerance thanks to yarn interlacing. With their high stiffness-to-weight and strength-to-weight ratios, braided composites are attractive for aerospace and automotive components as well as sports protective equipment. In these potential applications, components are typically subjected to multi-directional static, impact and fatigue loadings. To enhance material analysis and design for such applications, understanding mechanical behaviour of braided composites and development of predictive capabilities becomes crucial. Significant progress has been made in recent years in development of new modelling techniques allowing elucidation of static and dynamic responses of braided composites. However, because of their unique interlacing geometric structure and complicated failure modes, prediction of damage initiation and its evolution in components is still a challenge. Therefore, a comprehensive literature analysis is presented in this work focused on a review of the state-of-the-art progressive damage analysis of braided composites with finite-element simulations. Recently models employed in the studies on mechanical behaviour, impact response and fatigue analyses of braided composites are presented systematically. This review highlights the importance, advantages and limitations of as-applied failure criteria and damage evolution laws for yarns and composite unit cells. In addition, this work provides a good reference for future research on FE simulations of braided composites.
