Abstract
The strain rate sensitivity and gage length dependency of Bamboo fiber are investigated using Instron type tensile testing machine at room temperature. Ultimate tensile strength decreases with increasing gage length. In-situ observation of specimen surface during tensile test has been made to characterize the microscopic deformation and the fracture behavior of Bamboo fiber extracted using steam explosion method. Some kinds of such interfacial debonding are observed into fiber bundle. Simultaneous extension of delamination crackings and the fiber breakage, and subsequent incorporation of their microcracks into the main crack are observed.
