Abstract
A study is made of unidirectional carbon-fiber-reinforced composites with both thermosetting and thermoplastic matrices. Experimental data on acoustic emission for unidirectional fiber composites with a crack is presented in the form of an exponential dependence of the number of AE signals on the stress-intensity factor. The increase in the size of the damage zone across the layers of the composite turns out to be linearly dependent on loading time (and, thus, on Klc), in contrast to the usual quadratic dependence along the layers.
