The deformation and fracture characterizations of natural fibers under high temperature are useful in product the degradable composites. Elastic responses and tensile properties of bamboo fibers prepared by steam explosion method were investigated at elevated temperatures. Fiber strength and fiber ductility distinctly decreases with increasing temperature. Additional material's tendency to brittle failure at elevated temperature is caused by heat decomposition for cellulose. Tortional deformation of bamboo fibers were found out at high temperature above 160℃. Once a fiber was plastically deformed under high temperature, it couldn't recover its original fiber shape at room temperature.
