High stress abrasive wear study on bamboo

High stress abrasive wear of bamboo in mainly two directions parallel and perpendicular to the fibre direction has been determined by using a Suga abrasion wear tester. Bamboo is a unidirectional natural composite. Unidirectional cellulosic fibres in bamboo provide unique directional wear properties. The anisotropic abrasive wear behaviour was observed due to difference in fibre vascular bundle orientation present in bamboo. Wear anisotropy of bamboo depended on load and abrasive grit size.Wear anisotropy dependence on load can be represented by the following relation:WTTWLL=−aL2+bL−cRelation between wear anisotropy and grit size is found to be as follows:WTTWLL=−eS3+fS2−gS+hWeight loss dependence on grit size for bamboo follows the following equationW=xS2−yS+zW=xS2−yS+zWorn surfaces of bamboo and its debris were observed by using a SEM and discussed in this paper.
