Abstract
In recent years there has been a rising interest and researches in using high strength natural fibers as filler for biodegradable resin matrix composites. The present work deals with mechanical elements of deformation and fracture behavior of bamboo fiber bundle(Phyllostachys pubescens). The steam explosion treatment was applied to extract the bamboo fibers from natural bamboo. Dynamic tensile test, using a Hopkinson bar of low impedance bar(polyvinyl chloride, PVC) setup and conventional quasi-static test were carried out with this fiber. The tensile stress-strain response of bamboo fiber was observed elastic material response. A maximum strength bamboo fiber was given from near the outside of bamboo culm. Fiber strength decreased with increasing gage length in test piece. Experimental results show the fracture strength of the bamboo fiber has strong dependence on its volume. The PVC long bar was ascertained to be quite useful for a device measuring stress waves in dynamic tensile tests, if the behavior of the wave propagation in the PVC bar such as the decreasing rate of the wave amplitude and the propagation velocity are obtained by wave propagation pre-experiment beforehand.
