IMPACT TENSILE PROPERTIES OF SUPER FIBER YARNS

Toshiyasu Kinari; Akihiro Hojo; Sukenori Shintaku; Nobuo Iwaki

ABSTRACT A new impact tensile testing apparatus based on the one-dimensional elastic-stress-waves theory has been developed. It is mainly composed of an input bar to transmit load to the specimen and to measure dynamic elongation of the specimen, a pair of load cells to measure the load of the specimen and a striker energized by compressed air. It is designed to investigate dynamic mechanical properties of super fiber yarns, such as aramid fiber and carbon fiber that have small breaking elongation compared with most synthetic fibers. Using this apparatus and an universal testing machine, stress-strain curves of several kinds of aramid fiber yarns and a carbon fiber yarn are obtained at the strain rates ranging from 10-3/s to 103/s.
