Fiber reinforced polymers are used in a wide range of applications involving impact, including automobile and aerospace components, consumer products, and industrial products. These materials, however, are difficult to characterize under high strain rate conditions, particularly at strain rates exceeding 1000 1/second. This difficulty occurs due to numerous factors, including specimen design and size factors, absence of appropriate test equipment for high strain rate characterization, and interpretation of measurement data. This presentation presents high strain rate testing experience on short fiber injection molded thermoplastics. We present stress/strain behavior at different strain rates, and discuss the effect of specimen design and different methods to evaluate high strain rate response and failure.
