New rigid material from Swiss scientists can absorb vibration and noise

Researchers at the Swiss University of Technology Zurich have presented a unique composite material that effectively absorbs noise and vibration. It has a rigid structure, which makes it suitable for applications such as aerospace engineering.
It consists of ultra-thin rubber-like layers based on polydimethylsiloxane bonded with silicon and glass plates 0.2-0.3 mm thick. The damping polymer layers are less than 1% of the total volume of the material. Also, the polymer used is thermally stable and can withstand a wide range of temperatures without changing its damping properties.
The operation of trains and automobiles produces vibrations that can destroy structures. Engineers usually use damping materials, but they can increase the weight and cost of products and do not always provide the necessary efficiency.
The scientists are confident of the wide range of applications for their invention, from window panes to car bodies and aerospace components. In addition, the technology is easily scalable, making it possible to create panels as small as a few square meters with minimal effort.
