C01 – Sandwich elements with kinematic and building-related physical functionalities

C: Integrative components

The core topic of project C01 is the maximization of benefits of sandwich application in construction and architecture

Funding Phase I

To this end, existing but mostly passive structures are converted into multifunctional sandwich elements.

Sandwich structures combine different materials into a new hybrid compound. Because of their advantageous properties they are already an important part in constructive lightweight engineering. They enable the construction of high-performance lightweight shell structures. Sandwich structures currently are divided into two categories: Structural sandwiches primarily fulfill structural tasks, while cover panels are used for design and protective purposes.

In civil engineering and architecture, sandwich panels are widely used as exterior or interior cover elements. Previous and current research shows that sandwich has a much larger potential, which is why C01 looks at two topics of special interest: Active shape change and integration of building-related physical functions. Goal of C01 is the design of innovative sandwich elements with kinematic and physical functionalities.

The following questions are looked at in C01:

  • What potential for shape-change is offered by novel sandwich concepts
  • How can building-related physical functionalities be integrated into sandwich structures?

Shape-changing lightweight sandwich elements can help to reduce the mass of the skin and necessary substructure, and open up new architectural design possibilities. With a micro- to macroscopic shape-change, the building can adapt to changing environmental and structural conditions. Mobile structures with a small number of kinematic degrees of freedom can enable the coordinated and parallel actuation of numerous small surface elements, which in turn influence physical properties like translucence or ventilation.
