Abstract Tufting of preforms increases the resistance of the laminated composites to delamination. Draping of the preforms is clearly modified by the presence of tufting threads. A simulation approach for the forming of tufted textile reinforcement stacks is proposed. It determines the state of the tufted preforms after forming and in particular the possible wrinkles. The layers of textile reinforcements are modeled by stress resultant shells. Tufting threads are modeled by rod chains that can s...

Abstract Draping of composite textile reinforcements on a square box was analyzed experimentally and by numerical simulation. This forming is difficult for fabrics with continuous fibers due to the quasi inextensibility of the fibers. It is shown that the feasibility of draping on a square box with a large depth depends on the weave pattern of the textile reinforcement. Simultaneous forming of several plies without defects is also obtained. A simulation approach based on stress resultant shell f...

Different approaches for the simulation of wrinkling during forming of textile reinforcements are presented. It is shown that 3D finite element modeling requires the consideration of an additional bending stiffness of the fibers. In shell-type modeling, the bending stiffness is important because it conditions the size of the wrinkles. Different methods to take into account the bending stiffness independently of the tensile stiffness are presented. The onset and development of wrinkles during for...

When a thick laminate is subjected to bending, under certain boundary conditions, wrinkles may appear and develop due to the inextensibility of the fibers. Wrinkling is one of the most critical defects in composite manufacturing. Numerical simulation of the onset and growth of such wrinkles is an important tool for defining optimal process parameters. Herein, several bending experiments of thick laminates are presented. They were found to lead to severe wrinkling and delamination of different ki...

De nombreux composites a base de renforts dits 3D, au sens qu’ils incluent des renforts dans l’epaisseur, ont ete developpes pour surmonter des problemes inherents aux stratifies conventionnels, tels que leur faible resistance a la delamination et leur faible tolerance aux dommages lors de l’impact. Le renforcement dans l’epaisseur peut-etre obtenu a l'aide de diverses technologies textiles, dont le tissage 3D, le tricotage3D et le tressage 3D, qui permettent de fabriquer ces renforts en une eta...
