Testing the mechanical properties of reinforcing fibers—such as carbon, glass, basalt, or ceramic fibers, as well as recycled fibers—is becoming increasingly important, as lightweight construction techniques are being used in more and more fields to conserve resources. A meaningful, fast, and reliable testing method is essential for quality control of these fibers. Single-fiber tensile tests serve this purpose. To quickly and easily determine the mechanical properties, it makes sense to clamp the fibers directly into suitable clamps and test them, rather than having to laboriously affix them to individual paper frames in accordance with ISO 11566. At the same time, the fineness of the individual fibers in the section of the fiber being tested should be determined—a vibroscopic measurement is used for this purpose. The WiBreak project is focused on developing a foundation for
standardization. More…
