Kamke Analysis of Calcutta bamboo for structural composite materials: physical and mechanical properties Received: 11 April 2005 / Published online: 4 August 2005 Springer-Verlag 2005 Abstract The objective of this study was to determine the technical feasibility of producing a structural composite from Calcutta bamboo. The first article on surface characteristics published in this series addressed pH, buffer capacity, wetting, and surface energy (Ahmad and Kamke 2003). In this pa- per, the physical and mechanical characteristics were considered for their variability with respect to location along the length of the bamboo culm, nodes versus internodes section, and radial versus tangential directions. The physical and mechanical characteristics were also compared to timber species commonly used in the manufacture of structural composites. The character- istics studied were found to have some variability at different locations, sec- tions, and directions. Calcutta bamboo was found to have similar physical and mechanical characteristics to commercial timber species in Malaysia and North America. Introduction Dendrocalamus strictus is commonly recognized as Calcutta bamboo (Farrelly 1984), but is also known as male bamboo (Tewari 1992), and solid bamboo (Anon 1992). Calcutta bamboo is the most widely used bamboo in India (Kumar and Dobriyal 1992), especially in the paper industry. It is also used in housing construction, basket making, mats, furniture, agricultural implements, and tools handles. It is the most common species of bamboo sighted in the Indian forest and is available in every state in India (Limaye 1952). This species M. Ahmad () Department of Bio-comp
