• Abstract:
  The goal of this program was to determine the effect of plastic media blasting (PMB), an alternative to chemical paint removal, on the fatigue life of 2024-T3 aluminum. Two surface treatments, anodized and alclad, of three thicknesses: 0.032 inch, 0.040 inch, and 0.050 inch were considered. A number of alclad and anodized aluminum panels of the alloy and thicknesses specified were subjected to four cycles of PMB. The blast parameters were identical to those used in a previous FAA program. Almen strips tests were performed to quantify the blast intensity. A fatigue testing program was conducted on both the 'as received' and the PMB treated material. Reductions in mean fatigue life were observed for all materials tested after PMB treatment. These reductions were statistically significant for the 0.032 alclad and 0.040 anodized specimens.
