Variation in Fibre Wall Structure in Bamboo

Abstract

The degree of polylamellation in the fibre cell walls of the bamboo Phyllostachys virideglaucescens has been investigated. The extent of polylamellation was found to be influenced by position of the vascular bundle in the culm wall, in certain positions by age of the culm and, most strikingly, with position within the vascular bundle. The number of wall lamellae was variable but tended to be greatest in fibres adjacent to either vascular elements or ground tissue at the periphery of the fibre bundles. A similar pattern of variation in fibre wall lamellation was also observed in two other species of bamboo. The characteristic pattern of fibre wall lamellation probably influences mechanical properties and warrants further investigation.

Variation of mechanical properties of single bamboo fibers (Dendrocalamus latiflorus Munro) with respect to age and location in culms

“…This behavior may be partly explained by the typical multilayered cell wall structure of bamboo fibers (Parameswaran and Liese 1976). It is well established that mature bamboo fibers have more cell wall layers than the young ones (Murphy and Alvin 1992;Liese and Weiner 1996), and this is illustrated also by the micrographs in Figure 4. The polylamellate cell wall structure leads to a better fracture resistance and facilitate an inner slippage among cell wall layers during tension.…”

Bamboo fibre reinforced biocomposites: A review

“…Non cellulosic components have enough contribution to fibre properties such as strength, flexibility, moisture, and even density [37]. The unidirectional arrangement of bamboo fibres in tissues and cell wall structure of bamboo is one of unique property of bamboo [38][39][40]. Bamboo fibres possess alternate broad and narrow polylamellate structure with alternating broad and narrow lamella as compared to sandwich like structure of wood fibre [41,42].…”

Cell wall structure and formation of maturing fibres of moso bamboo ( Phyllostachys pubescens ) increase buckling resistance

“…The fibres are the main components determining the mechanical properties of bamboo owing to their unidirectional arrangement in the tissue as well as their unique cell wall structure [3,4]. In contrast to the sandwich-like structured secondary wall of wood fibres with a dominating middle layer (S1 -S3), the bamboo fibres possess a much finer multi-layered wall structure with alternating broad and narrow sublayers [5,6].…”
