“…Stretched reinforcement yarns can be inserted into such fabrics in both warp and weft direction. In weft direction, integration can be ensured across the entire fabric width or across parts of the fabric (partial weft), which is important for local adaptation . The connection of individual reinforcement layers by means of the loop yarn allows the manufacture of reinforced fabrics with two or more reinforcement layers .…”

In this comparative study two sensor yarns, such as carbon filament yarns and carbon nanotube coated glass filament yarns are analyzed regarding their electrical property changes during textile manufacturing into multi-layer weft knitted structures as well as during compression molding into a composite plate due to the different electro-mechanical behavior, various sensitivities, and changing ways of acting as an in-situ sensor: yarns act either as a conductive fiber itself (carbon) or as an electrical conductive sizing (CNT-coated glass). Both sensor yarns under investigation have to be considered differently with regard to changes in the electrical conductivity due to mechanical loading during textile processing and possible healing of cracks during compression molding.

“…Due to their light weight, superior mechanical properties, anti-corrosion properties, reduced tooling costs, higher energy absorption capability as well as better damping properties compared to metallic materials, fiber-reinforced plastics (FRPs) offer great potential for the production of morphing structures [14][15][16][17].…”

The process of integrating smart materials into fiber-reinforced plastics has been used increasingly to create different high-performance products for lightweight applications. This paper presents the development of an adaptive morphing wing based on fiber-reinforced plastics with shape memory alloys integrated into the reinforcing fabrics. Two types of preforms with varying numbers of integrated weft yarns in shape memory alloys were manufactured for a wing structure on a weaving machine using the pleated woven fabric technology. Subsequently, the realized preforms were infiltrated by a thermoset matrix and characterized mechanically to derive a preferred variant. After developing the adaptive morphing wing, its deformation behavior was characterized by varying current flow and time through shape memory alloys. Results revealed that maximum deformation of the investigated adaptive morphing wing was achieved at a current flow and time of 1 A and 60 s, respectively.

“…Since the PACS are characterized by a predominantly biaxial property profile, high stiffness in one direction and low stiffness (flexibility) in the other direction, biaxial structures are particularly advantageous. Weaving is predestined for transverse and longitudinal reinforced biaxial structures and semi-finished products for FRP [5]- [10]. So far, there have been two possible solutions for the integral production of closed-cell woven structures.…”

Abstract. Flexible cellular 3D structures with structure-inherent compliance made of fiberreinforced composites have repeatedly aroused the interest of international research groups. Such structures offer the possibility to meet the increasing demand for flexible and adaptive structures. The aim of this paper is the development of cellular 3D structures based on weaving technology. Considering the desired geometry of the 3D structure, algorithms are developed for the formation of geometry through tissue sub-areas. Subsequently, these sub-areas are unwound into the weaving level and appropriate weave patterns are developed. A particular challenge is the realization of compliant mechanisms in the woven fabric. This can be achieved either by combining different materials or, in particular, by implementing large stiffness gradients by means of varying the woven fabrics thickness, whereas differences in wall thickness have to be realized with a factor of 1:10. A manufacturing technology based on the weaving process is developed for the realization of the developed 3D cellular structures. To this end, solutions for the processing of hybrid thermoplastic materials (e.g. tapes), solutions for the integration of inlays in the weaving process (thickening of partial areas), and solutions for tissue retraction, as well as for the fabric pull-off (linear pull-off system) are being developed. In this way, woven cellular 3D structures with woven outer layers and woven joint areas (compliance) can be realized in a single process step and are subsequently characterized.
