Overlap Fix – High performance textile structures for composites through open reed weaving

Inventors of the RWTH Aachen University filed a patent relating the production of the multiaxial enforcement fabrics for textile composites with ORW (Open Reed Weave). To avoid load path interruptions in composites with textile enforcement, an overlapping of two yarn systems in the textile, by means of a special weaving pattern, leads to continuous load path in bias direction, reaching a “Triaxial” fabric, which is the main approach of the investigation. The Angle of additional reinforcement direction is adjustable and the calculated necessary overlapping is 16.28 mm length.
The system´s capability was verified by conducting three-point bending tests. These are performed varying the overlapping length, testing carbon and glass fibers and using reference samples as follows: [0/90°] fabrics and [0/90/45°] fabrics with continuous reinforcement. The results were successful in all cases. PROvendis offers licenses for interested enterprises on behalf of the University of Aachen.
