A concept of a nature-inspired pedestrian bridge which tries to merge architectural, structural and manufacturing aspects in an optimized way is presented. The 18.0-m-span bridge is designed as an overhead spatial frame of a complex double-curved shape, which is composed of twelve modules consisting of lightweight carbon fiberreinforced polymer (CFRP) sandwich construction. The modules are fabr...

Natural fibres have recently become an attractive alternative to synthetic in the implementation of polymer composite structures. Inherent flaws within natural terms their constituent contents (hemicellulose, cellulose, and lignin) reduce compatibility these with matrices. In this study, effects chemical treatments on hemp resulted polyester matrix are investigated. The were treated alkali (0–1...
