摘要：

A new testing method using a mini split Hopkinson tensile bar was employed in the impact tests of Lincoln wool fibers. Stress-strain curves of Lincoln wool fibers subjected to impact loadings at strain rates in the order of 10(2) s(-1) were obtained, which fill the gap in the impact data for Lincoln wool fibers. For comparison, quasi-static tests were also carried out with a single Lincoln wool fiber using a Micro-Tester. Stress level was observed to increase with increasing strain rates.
