An experimental investigation concerning the effect of AFP defects on progressive damage in CFRP coupons

Manufacturing of composite laminates using the fiber placement process introduces possibility several types defects and features that are not present in traditional hand-layup fabrication techniques. The effect these on structural performance failure has been fully investigated, especially for those with small geometrical features. innovation lies advanced methods to capture generated during manufacturing processes which can be used determine if warrant immediate repair ensure part integrity. Several configurations may occur automated (AFP) were inserted within coupons. Acoustic emission (AE) was employed as a nondestructive evaluation technique investigate correlations between mechanical properties damage propagation tension 3-point bending tests. Digital Image Correlation (DIC) utilized monitor progression test.
