Long-span Fibre Composite Structures

Research Project 11 (RP 11)

BUILDING SYSTEM AND MATERIAL SYSTEM DEVELOPMENT FOR LONG-SPAN, FIBRE COMPOSITE STRUCTURE

The project aim is to develop coreless wound fibre composite building systems with improved overall performance and reliability. The four main challenges of a coreless wound fibre-reinforced polymer (FRP) building system are: joint design, understanding the structural system, environmental impact and the integration into an architectural concept.

Higher stresses can accumulate at the joints, which makes the connections one of the key challenges in the structural system. They must be addressed in order to improve the overall performance and efficiency of the system. In the structural design phase of coreless wound filament structures (CFW) significant abstractions are made that can lead to a more conservative understanding of the system. The only way to improve the overall understanding of the structural system is to do real world measurements. To achieve this over the lifetime of a structure, a structural health monitoring (SHM) system will be included in the FRP components. The environmental footprint of the material is another challenge. This project will address possible, sustainable material alternatives to the carbon-/glass fibre epoxy material systems.

For a holistic assessment of these challenges, they need to be architecturally integrated within the overall building system. Therefore, this project aims to develop integrated joining, sensing and material strategies.
