Abstract: Milliken contracted Southwest Research Institute1 (SwRI1) to conduct blast pendulum tests on various panels. The blast pendulum allows one to investigate a material's capability of mitigating sample deformation and bulk structural loading that result from "close-in2" blast loading. The methodology is based upon placing a sample in a semi-rigid frame. The frame is supported by large supports that are free to rotate about a fixed position. Based upon the angular motion, the momentum transferred into the sample can be determined. The pendulum is most useful for looking at plate coatings which hopefully can reduce the plate deformation and the overall momentum transferred into a structure. SwRI conducted a total of four tests on September 5, 2007, using the blast pendulum at its remote site near Yancey, Texas. A representative from Milliken witnessed each test. None of the tests resulted in perforation of the target assembly, and their swing angles and deflections were considerably less than those of a baseline 3/8-inch mild steel target performed the next day (47.2-degree maximum swing with 4.53-inch maximum plate deflection) versus the best Milliken combination that showed a 41.8-degree maximum swing with 2.64-inch maximum plate deflection.
