Advanced Lightweight Structures

The module Advanced Lightweight Structures concentrates on building materials systems, like carbon fiber pre-stressed concrete elements that greatly reduce the weight of precast bridge and buildings elements. Here, the key criteria are the development of economically affordable, durable and fire-safe systems.

An additional focus in this module lies in developing materials and systems for reducing the emission and transmission of sound and vibration. One main goal is the reduction of sound transmission in lightweight systems, which are experimentally characterized and analyzed in Empa’s new acoustic testing lab.
