A Singapore institute has developed a novel eco-friendly sandwich panel for cost-effective sound damping in electro-mechanical systems. The composite sandwich panel replaces traditional synthetic materials such as polyurethane foams with a mechanically stronger, injection mouldable and 3D printable structure with tunable sound, vibration, mechanical and heat absorption properties.
The institute is interested in potential licensing opportunities with MNEs/SMEs of all sizes.
The rapid construction and development of the global built environment has led to serious noise pollution, with adverse effects on personal health, the environment, productivity and the reliability of electronic systems and other mechanical structures. As sustainable construction and development becomes an increasingly significant goal in the evaluation and promotion of the electro-mechanical systems used in buildings, manufacturing and work environments, it has become imperative to find cost-effective and environmentally friendly solutions that can help to reduce the noise pollution.
The eco-friendly sound damping sandwich panel developed by the Singapore institute is superior to traditional synthetic materials such as polyurethane foams which are toxic, feature poor mechanical strength, unable to absorb sound and control vibration at low frequencies, difficult to recycle and usually, end up in landfills. The novel composite sandwich panel is a mechanically stronger, injection mouldable and 3D printable stand-alone mechanical structure that is made out of recyclable materials and further customisable to be effective for a wide range of sound damping applications.
The sandwich panel for sound damping in electro-mechanical systems has been developed with the following characteristics:
- Multi-layered design to absorb sound and vibration at both high and low frequencies
- Injection mouldable and 3D printable layered structures
- Mechanically stand-alone structures
- Polymer resins and fillers can be used from natural materials
- Tunable sound, vibration, mechanical and heat absorption properties
The technology will find applications in commercial manufacturing industries that require sustainable, customisable and cost-effective acoustic damping and vibration control. The technology is suitable for applications such as:
- Electronic systems and/or components
- Heavy machinery
- Manufacturing factories
- Buildings, construction and renovation sites
- Food courts and hotel kitchens
- Automobiles, rail, air and sea transport vehicles
The Singapore institute seeks licensing partnerships with industrial players (MNEs/SMEs of all sizes) to commercialise this technology.
The advantages of the technology include:
- Flexible and modular design
- Cost-effective fabrication methodology
- Sustainable and recyclable material structures
In the midst of provisional patent application in Singapore.
The Singapore institute seeks to partner industry players (SMEs of all sizes or MNEs) through licensing collaboration.
The partner could license the technology to further develop it into new product/service to serve the needs of its customers.
