Building System and Material System Development for Long-Span, Fiber-reinforced Composite Structures

IntCDC Research Project 11-1

Innovating the coreless filament winding building system

The project developed coreless, filament-wound fiber-reinforced composite structures for long-span applications to achieve an increase in overall performance. Central aspects investigated in the project are:
- development of joint systems
- structural design strategies
- environmental impact
- architectural conceptualization

Connections are critical because changes in fiber direction and the accumulation of tension at these locations limit the mechanical performance and efficiency of the entire system. Structural design requires a comprehensive strategy between simulation and structural testing, as simulations cannot fully represent the complexity of the system. The use of fiber optic sensors and equivalent novel methods can provide much more insight into structural behavior. Another challenge is the environmental impact of the traditionally used carbon/fiberglass epoxy materials. Therefore, the project explored alternative materials and identified more sustainable options while quantifying the significance of bio-based epoxy systems. Finally, these challenges were holistically evaluated for architectural integration into the building system. As a result, the project developed methodological strategies to make the conceptual building system a future-proof solution for sustainable and efficient long-field structures.
