In a collaborative effort between Texas A&M University and Sandia National Laboratories, researchers have significantly improved a new joining technology, interlocking metasurfaces (ILMs), designed to increase the strength and stability of a structure in comparison to traditional techniques like bolts and adhesives, using shape memory alloys (SMAs).
ILMs offer the potential to transform mechanical joint design in manufacturing for aerospace, robotics and biomedical devices.
"ILMs are poised to redefine joining technologies across a range of applications, much like Velcro did decades ago," said Dr. Ibrahim Karaman, professor and head of the Department of Materials Science and Engineering Department at Texas A&M.
"In collaboration with Sandia National Laboratories, the original developers of ILMs, we have engineered and fabricated ILMs from shape memory alloys. Our research demonstrates that these ILMs can be selectively disengaged and re-engaged on demand while maintaining consistent joint strength and structural integrity."
The findings can be found in Materials & Design.
