Adaptive metaComposites: modeling, prototyping, manufacturing and reliability for vibroacoustics

该项目由GAUS（加拿大舍布鲁克大学）、FEMTO-ST研究所（法国弗朗什-孔泰）和LTDS（法国里昂中央理工学院）合作开展，旨在开发一种新的“智能元复合材料”概念，即主动-被动智能复合材料，用于声音和振动应用。这种超复合材料结合了开孔泡沫的自然吸收（被动部分）和适当定位和电子控制的活性内含物（电活性材料），以确保在整个可听频率范围内的最大声学性能。代表隔音的主要挑战的低频域更受关注，因为在该范围内，常规处理实际上是低效的。

This project, in collaboration between GAUS (University of Sherbrooke, Canada), FEMTO-ST Institute (Franche-Comté, France) and LTDS (École Centrale de Lyon, France) aims at developing a new concept of "smart meta-composite", namely an active-passive smart composite, designed for sound and vibration applications. This meta-composite combines the natural absorption (passive part) of open cell foams and active inclusions (electro-active materials) suitably located and electronically controlled to ensure maximum acoustic performance over the entire audible frequency range. The low frequency domain, which represents the major challenge of sound insulation, is more particularly concerned, since in this range conventional treatments are practically inefficient.
