SFB 639:  Textile-reinforced Composite Components for Function-integrating Multi-material Design in Complex Lightweight Applications

• Subject Area: Mechanical and Industrial Engineering
• Term: from 2004 to 2015
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 5485977

Lightweight structures using textile-reinforced composite materials offer numerous advantages over conventional designs and open up new fields of innovation, especially in vehicle and machinery engineering. Outstanding importance is here to be attached to the functionintegrating character of multi-material textile systems. The relatively new group of textile composite materials with thermoplastic matrix is predestined for efficient high-performance applications in the most varied branches of industry. Alongside the considerable weight reduction, they feature above all high strength and rigidity, positive damping and crash properties, broad diversity of textile technologies, economical manufacturing, and suitability for both small and large-series production.
From the point of view of materials science, constructive design and also technology, the variability of textile composites in combination with different materials has been investigated at best in only individual aspects to date and is yet to be exploited universally.
The goal of the Collaborative Research Centre is to elaborate scientific foundations and methods for the development and use of innovative textile composites for multi-material applications characterised by a high level of functional integration. For this the total process chain "from filament to component" is to be permeated in theory and realised exemplarily.
With its close relations to non-university research institutions, especially the TU Dresden embraces this Collaborative Research Centre. It is an ideal location for treatment of the envisaged research topics not least on account of its unique standing in the field in the German-speaking region. Interaction with the traditional industrial and textile research activities in the local region permits the Collaborative Research Centre to be seen as an innovation motor in the field of technical textiles, inducing sustained growth for the Saxon region, especially in respect of modern motor vehicle engineering.
