In order to understand the tensile properties of polyethylene naphthalene (PEN) fiber bundles at different strain rates, 25 specimens were tested using an MTS load frame and an Instron drop-weight impact system. Six different strain rates (1/600, 40, 80, 120 and 160s-1) were adopted in the tests and the corresponding tensile stress-strain responses of the fiber bundles were investigated and discussed. The experimental results showed that the tensile strength of fiber bundles increase with the strain rate while the peak strain decreases with the strain rate.
