Higher Efficiency in Fiber Lightweight Construction

Weaving Local Reinforcements into Textiles

Fiber composite materials offer high stability as well as low weight, which makes them indispensable for lightweight construction. If compared to other types of production materials, their production costs are high, which has been an obstacle to broad implementation in industry, until today.

„A new weaving technique has been available for three years now, called Open Reed Weaving. It is suited to integrate local reinforcements into reinforcing textile materials. The technique reduces the number of steps required for processing, and diminishes the amount of waste,” explains Dr. Christopher Lenz, who is an alumni at the ITA institute of textile engineering (Institut für Textiltechnik) at RWTH Aachen University. Dr. Lenz was nominated for this year’s Otto-von-Guericke Award, presented by the German Federation of Industrial Research Associations (AiF), for his research findings in Open Reed Weaving. Within the framework of the AiF project “Multiax-Structure: Single-stage production of local reinforced textile structures on the basis of multiax-fabrics”, he developed the knowledge and skills necessary to pave the way for large-scale application of Open Reed Weavings.

„So far, little has been known about the technology’s potential, how to apply it in industrial productions and the integration into well-established processes,” adds Prof. Dr. Thomas Gries, Director of the ITA. He claims that the results achieved in the context of the nominated IGF-project will finally allow for industrial application of this process. In particular, the software tools developed in the project will make the technology attractive for medium-sized enterprises.

Thorsten Overkamp, head of carbon fiber weavers C. Cramer, Weberei, GmbH & Co. KG in Nienborg, Germany, is delighted about the IGF results: “The technology has a tremendous potential. Particularly attractive for our medium-sized company are the software tools, developed during the project. They facilitate the access to this new technology.”
