Application of graphene enhanced foam materials for noise damping in vehicles

Research Project, 2022 – 2023

Purpose and goal: Current noise absorbent materials are composed by foam or fibers, which have a limitation in terms of low frequency absorption and on the temperature range control. In many cases, very thick materials must be used to have low frequency noise control and a thermobarrier must be added to avoid themoincidents, which will impact the overall acoustic performance of the material.
The goal of the project is to evaluate the use of graphene based materials to overcome the limitations of the current acoustic materials. Expected results and effects: Few studies on the literature shows that the use of graphene on foam materials boosts the acoustic efficiency on the lower frequency, but, when graphene is applied on a carbon based fiber the low frequency efficiency can be combined with a high temperature resistant material, creating a new and innovative solution for noise control.
