Blast Resistant FRP Composite Designs & Verification

Professor Robert Asaro

Professors Asaro, Hegemier and Kim are working with the Office of Navy Research on concept designs of the new DDX deckhouse-steel connections, related to the U.S. Navy's newest class of destroyers, the DDG 1000. Hybrid joints are subject to complex internal stress states and are critical in terms of how they transfer loads between the massive steel hull structures and the lower density fiber reinforced polymer (FRP) composite deckhouse structure - - these researchers have impressive experience in this area. In addition to the study of joints, another team is evaluating blast damage vulnerability of the deckhouse structure. The Navy has plans for the production of three DDG 1000's.
