Researchers design steel analog of well-known fastener
Hook-and-loop tape is the generic name. But everyone knows the plastic fastener that can be reused and repositioned endlessly as Velcro. Now, German engineers have developed industrial-grade analogs for automotive and other applications. Made from steel, the newly patented fasteners can operate at temperatures as high as 800° Celsius and at tensile loads of up to 35 metric tons per square meter.
Industrial companies approached the Technical University of Munich’s Institute of Metal Forming and Casting four years ago about developing the new connectors. They’re patterned on the burrs that some pl
