Multiaxial damage identification of angle-ply laminates using acoustic emission and other online monitoring techniques

The aim of this research is the combined use of acoustic emission with other online monitoring techniques in order to identify the damage sequence of carbon fiber reinforced epoxies. Initially, common lay-ups were tested and their acoustic emission was monitored and analyzed with respect to the developing damage, in order to identify basic damage modes. Following this, angle-ply laminates were tested to characterize the damage evolution under multiaxial stress states with the use of acoustic emission and supporting techniques.
