摘要

A review of literature about the effects of fiber property distributions and jaw placement on HVI testing results is followed by a description of and results from an HVI computer simulator. A novel analysis of previously published data shows that mean and standard deviation of breaking load and elongation of a prepared test specimen vary with distance from the specimen clamp. Results of an HVI simulator based on theoretical considerations described here agree with experimental results. Placing jaws at different percent span lengths may introduce error into strength measurements by including a different subset of fibers with different fiber properties in each test. In addition, the MCI HVI air orifice used in strength tests may preferentially remove fiber crimp according to fiber elongation, which would result in an apparent increase in bundle strength.
