Engineered bamboo: state of the art

Abstract

Bamboo is a rapidly renewable material that is available globally and comparable in strength to modern structural materials. The widespread use of bamboo in construction is limited by the inherent variability in its geometric and mechanical properties, and the lack of standardisation. Engineered bamboo aims to reduce the variability of the natural material and is processed and manufactured into laminated composites. Although the composites have mechanical properties similar to other structural materials, the products are currently limited to architectural applications. A field of research on engineering bamboo is emerging with the aim to demonstrate and expand its use to structural applications. To summarise the state of the art, a review of published research is presented with the focus on two types of engineered bamboo: bamboo scrimber and laminated bamboo. The materials are compared with structural timber and laminated veneer lumber to demonstrate the potential applications and practical use.
