Weft-knitted fabrics offer an excellent formability into complex shapes for composite application. In biaxial weft-knitted fabric, additional yarns are inserted in the warp (wale-wise) and weft (course-wise) directions as a reinforcement. Due to these straight yarns, mechanical properties of such better than those unreinforced fabrics. The forming process flat 3D preforms is challenging requires numerical simulation. this paper, behavior simulated by means macro- meso-scale finite element...
The use of thermoplastic components with a complex three-dimensional (3D) shape, manufactured efficiently thermo-presses, has been increased steadily. Flat knitting technology using reinforcing hybrid yarns in the horizontal and vertical direction is especially suited for producing near-net-shape or fully-fashion multilayer weft knitted fabrics – MLGs (abbreviated from German word Mehrlagengestrick, meaning fabric). other advantages manufacturing such MLGs, flat technology, are reduced waste...
Shape memory alloys (SMA) are a promising material class for active lightweight structure applications with movement functionality. Due to their high activation energy potential and good processability in wire shape, they well suited application actively deformable, fibre-reinforced composite structures. In order generate large deflections from the limited deformation of SMA, detailed analysis mechanisms is required. this work, bionic approach pursued, investigating characteristics...
Shell-rib structures made of textile-reinforced composites are used in a wide range applications to increase bending, buckling and torsional stiffness. Such usually manufactured differential construction at the preform level by assembling several textile or component subsequent joining separately shells stiffening structures. Integral production is one way overcome disadvantages forenamed methods, such as high manual effort, failure during fiber distortion. Weft-knitting technology excellent...
Constantly increasing prices for raw materials and energy as well the current discourse on reduction of CO2-emissions places a special emphasis advantages lightweight constructions its resource conserving production methods. Fibre-reinforced composites are already seeing number applications in automobile, mechanical engineering. Future within named areas require greater material efficiency therefore manufacturing methods textile preforms enabling an optimal arrangement reinforcing fibres...
Adaptive structures based on fiber-rubber composites with integrated Shape Memory Alloys are promising candidates for active deformation tasks in the fields of soft robotics and human-machine interactions. Solid-body hinges improve behavior such composite structures. Textile technology enables user to develop reinforcement fabrics tailored properties suited hinged actuation mechanisms.

Mostly due to the cost-intensive manually performed processing operations, production of complex-shaped fibre reinforced plastic composites (FRPC) is currently very expensive and therefore either restricted sectors with high added value or for small batch applications (e.g. in aerospace automotive industry). Previous works suggest that successful integration conventional textile manufacturing processes FRPC-process chain key a cost-efficient complex three-dimensional (3D) FRPC-components...
