Abstract

Two methods - the empirical constants and decibel drop - for sizing defects, which are very close to the probe, in fiber reinforced composites using the pulse echo ultrasonic inspection method were developed and experimental data obtained. The methods relate the reduction in signal amplitude from a defect which is smaller than the probe diameter to the signal from a defect which is equal to or larger than the probe diameter. The empirical constants method was confirmed to produce a higher accuracy than the decibel drop method.
