Biomimicry engineering: New area of tranformation inspired by the nature

摘要

Biomimicry engineering in civil engineering is a creative and innovative way that inspired by the nature to solve the engineering problem and transform it into new invention. This area is recognised to solve the multipart issues, create the green technology material, reduce the environmental impact and reduce the engineering cost. Nowadays, the biomimicry engineering area is expanded and produced a quality product such as airplane, ship, submarine and other historical product. The biomimicry engineering includes of mimic of shape, properties, method, principle and process. This paper shows a case study of the biomimicry engineering in concrete section. The new materials are replaced and mimic the natural coarse aggregate in concrete. The material is waste paper sludge ash and rubberwood dust. Both materials are produced and pelletised to become aggregate that have same size and shape. Having analysed their compressive strength and compared with normal concrete mix, it was found that both material had a good potential to mimic the natural coarse aggregate in concrete. Besides that, the innovation workflow of problem and solving biomimicry engineering are produced. The workflow is compared with other biology and architecture area to produce clear biomimicry engineering steps and suit with civil engineering. The biomimicry engineering index is developed to class the percentage of mimic to nature. The workflow is proposed for the engineer to inspire nature to cater the engineering problem. Finally, the area of biomimicry engineering is extended in all civil engineering section especially in structure and material engineering.
