Tensile loading rate effect on mechanical properties and failure mechanisms in open-hole carbon fiber reinforced polymer composites by acoustic emission approach

In this article, the effect of the tensile loading rate has been investigated on mechanical properties and failure mechanisms in open-hole carbon fiber reinforced polymer composites. For this objective, acoustic emission signals on standard specimens under tensile loading were acquired and analyzed by the wavelet packet transform (WPT) and the fuzzy C-Means (FCM) methods. Tensile tests were also performed on pure resin, pure fiber and composite...
