Description

In an effort to verify theoretical models which relate matrix cracking to strength reduction, acoustic emission (AE) was used to locate matrix cracking in flat graphite/epoxy cross-ply tensile coupons. Using independent test methods [1] it was discovered that errors of up to 2 inches were common in the AE data (specimen length — 8 inches). Dispersion of the AE event caused the AE analyzer location clocks to trigger on different phase components of the event [2,3].
