Abstract : During production of advanced composite structural parts, because of material manufacturing process anomalies, some typical defects, such a porosity and/or delaminations, may become embodied into the final product. In order to improve the accept/reject criteria for typical defects, AERITALIA's G.V.C. Laboratories have carried out a static/fatigue test program on specimens in which various porosity levels were simulated. Further, an attempt has been made to correlate mechanical performance with the ultrasonic energy absorption measures.
