Faculties at IIT Hyderabad’s Mechanical and Aerospace Engineering Department, Dr B. Venkatesham and Dr Surya, fabricated low thickness and strong acoustic panels mimicking this property using biomimetic design methodology. The team also developed a mathematical model and calculated optimised parameters, and then fabricated the test samples using systematic, controlled parameters. Subsequently, fabrication of a large sample was done.
They have used two different approaches and their respective prototype machines with two different kinds of materials. One prototype is for paper honeycomb based on indexed Honeycomb Before Expansion process, and another prototype machine is for polymer honeycomb structure, based on hot wire technique.
