Abstract:

This study investigates the effectiveness of a commercially available two-part fiberglass patching kit for repairing steel plates with cracks of varying sizes. The kit, produced by DuraPower Product Inc., includes a fiberglass patch, resin, and an activator, which serve as the adhesive for the repair. Four steel plates were tested: one without a crack and three with small (5 mm), medium (13 mm), and large (20 mm) cracks machined at the center. The repair process involved applying a fiberglass patch to each plate, and Non-Destructive Evaluation (NDE) using PZT-SLDV Lamb waves employed to assess the repaired specimens. The NDE results showed that the patching material significantly influenced wave energy transmission, with wave energy being more confined within the patch on the repaired surfaces. The study demonstrated that the repair process was effective in restoring the structural integrity of plates with varying crack sizes, successfully addressing defects of different lengths, and achieving good adhesion with minimal air bubble formation. This research provides valuable insights into the real-world applicability of the patching kit for repairing cracked steel surfaces.
