Abstract

This project can be summed up as the development of a process for laminating two or more sheets together, of the same or different thickness, with the interspacing of plastic polymers or other materials adhering to the internal surfaces, also known as - Vibration Damping Steel (VDS) -, to reduce noise and vibration induced in these sheets at various frequency ranges. This is the development of a new process and a new product as yet unprecedented in Brazil, which will enable the sound insulation of equipment such as motor vehicles, household appliances, and machinery in general, or sound insulation between different spaces as in the case of room dividers.
