Anisotropic abrasive wear behaviour of bamboo (Dentrocalamus strictus)

Unidirectional vascular fibre bundles present in bamboo provide unique directional abrasive wear properties. Wear anisotropy magnitude of bamboo is a function of load and abrasive grit size. Worn surfaces and debris after wear test were observed by using a SEM. It has been found that the debris generated were of fibrous type in longitudinal direction, which came out after ploughing and microcutting of vascular fibres, while in normal fibre direction, debris were of particulate type. This unique difference in the nature of worn debris explains the difference in abrasive wear behaviour in three different directions of bamboo.
