The development of near-net-shape 3D meshes for use in fiber-reinforced plastics (FRP) received the AVK Innovation Award in the "Research/Science" category (1st place). The team of scientists from the Institute for Textile Machinery and High-Performance Textile Materials Technology (ITM) at TU Dresden/Germany, with Dominik Nuss, Cornelia Sennewald and Prof. Chokri Cherif accepted the award at the JEC Forum DACH in Augsburg/Germany, on November 29, 2022.
With the development of the pull-off-free jacquard weaving technology including the technological know-how in the field of highly complex 2D and 3D fabric geometries, which has been established at the ITM for many years, Dominik Nuss has succeeded in including different yarn lengths locally into the fabric structure solely through targeted variation of the fabric weave. Therefore, it is now possible to produce new types of fabrics without additional draping, especially spherically curved fabrics, but also large-format spiral or even curved fabrics. The fact that the required near-net-shape geometry of the component to be reinforced can be reproduced with significantly reduced preforming steps is to be emphasized.
Continuous simulation aided engineering from CAD design to integrally woven 2D and 3D preforms by means of highly complex weave development for spatial constructions is unique at the ITM, which was indispensable for the development of these promising woven high-tech structures. This technology is new and has never been carried out in this way before. The fabric structures are characterized by a high innovation level due to their geometric diversity and purposes. It can be used in numerous applications and furthermore contributes to the development of completely new fields of application. The technology can be implemented on all jacquard weaving machines with only an additional device and the preform geometry is only determined by the control of the Jacquard machine. The preform geometry can be used in the full working width of the weaving machine.
