Bamboo tissue is approximately composed of 52% parenchyma, 40% fibers (sclerenchyma sheaths and separate fiber strands) and 8% conducting tissue (tubes). The ground tissue of a bamboo culm consists of parenchyma cells, with embedded vascular bundles composed off metaxylem vessels, sieve tubes with companion cells, and fibers. Microscopic Features of Bamboo (Moso and Guadua) 1), resulting in more ‘stripes’ on the tangential surface near the outside of the culm wall than on the inside (see difference between Fig. Similar to Guadua, the concentration of the vascular bundles near the outside of the culm wall is high (Fig. The nodal regions are small (due the small diaphragm), and do not result in a coarse surface after planing. Phyllostachys edulis or Moso has a reasonably fine grain, finer than Guadua due to its smaller vascular bundles. Macroscopic Features of Bamboo (Moso and Guadua) In the Dutch construction sector it is common practice to use KOMO-certificates one can hardly enter the market without having their product certified according to KOMO. Norway spruce and dark red Meranti were chosen because they are commonly used in the Dutch market, and are often used for exterior applications.Ĭertification Institutes which are accredited by the government, check if a product meets the requirements, and award the KOMO-certificate if it does. In order to provide a point of reference, the test results were compared to 2 wood species. The tests are performed on single, non-laminated strips, in order to obtain data on the bamboo material in its natural condition. Mechanical properties of Guadua and Moso, were tested according to the KOMO-certified standard, which is the most commonly used standard for outdoor construction applications in The Netherlands. Comparing Mechanical Properties of Bamboo Guadua angustifolia (Guadua) is hardly found in industrial manufactured products in the West (EU and USA), but since it is South America’s most important bamboo, and industrial activities are picking up, it is of interest to develop know-how on this species.īy testing these two bamboos, we will acquire more in-depth knowledge about the world’s 2 most important giant timber bamboo species.
