Integrative Methods for Hybrid Bio-fibre Timber Composite Systems

Research Project 12-3 (RP 12-3)

INTEGRATIVE COMPUTATIONAL DESIGN AND ENGINEERING METHODS FOR NOVEL HYBRID BIO-FIBRE TIMBER COMPOSITE SYSTEMS

This project develops an integrated computational design and engineering framework for hybrid bio-fibre timber composite structures. The framework combines computer vision, mechanical analysis, real-time monitoring, and situated visualisation to address two critical challenges: performance predictability and material efficiency in fully bio-based structural systems. Building on IntCDC's research in natural fibre composites, which have achieved structural weight reductions of up to one-fiftieth of equivalent concrete systems, the project addresses three fundamental limitations: unreliable and slow data integration, high material variability, and joint performance as the primary failure bottleneck.

The project advances natural fibre building systems and coreless filament winding towards circularity and resource efficiency, while developing multi-material systems that address structural performance and multi-agent fabrication. Combining design support with fibre-optic sensor monitoring, the approach leverages optimisation algorithms, redundancy distributions, and uncertainty visualisation to improve predictability and reduce material requirements. Real-time sensor- and vision-based feedback loops link fabrication data to the digital model, enabling cyber-physical prefabrication with on-the-fly adaptation of robotic process parameters and continuous, automated safety assessment. Novel fibrous joint geometries maintain fibre continuity while minimising stress concentrations. Modular system designs enable building stock retrofitting for urban densification. Software tools and validated datasets disseminated through IntCDC and DaRUS facilitate broader knowledge transfer and demonstrate pathways toward resource-efficient, circular building practices.
