Clustering effect on damage mechanisms in open-hole laminated carbon/epoxy composite under constant tensile loading rate, using acoustic emission

In the present research, damage mechanisms in the open-hole laminated carbon/epoxy composite have been investigated using the acoustic emission method. For such objective, standard specimens, made of the pure resin, the pure fiber and composites, were tested under tensile conditions, at a constant loading rate. Then, the clustering effect was studied in order to know which damages (debonding, fiber pull-out, delamination, matrix cracking and...
