ACOUSTIC EMISSION CHARACTERISTICS OF DAMAGE PROCESS FOR APMOC/EPOXY COMPOSITE LAMINATES

A detailed study of damage mechanism failure process for APMOCiepoxy composite laminates in different stacking sequences was conducted by use of acoustic emission monitoring. The results showed that the relationship between AE signal parameters and damage mechanisms can be established. Obviously,AE signal parameters being recorded can reveal the dynamic damage process of the laminates. The different AE parameters relate to the different damage process and mechanisms in the laminates.
