Composite naval structures have many advantages over more conventional ones including stealth, insulation, lower manufacturing cost, low maintenance and corrosion resistance and overall lower life-cycle cost. Specific applications depend on the type of ship, part of the ship (topside, hull, bulkheads, etc.), mission and anticipated environment. Surface and submersible naval structures are subject to a variety of threats including mines, torpedoes, air and underwater explosions, and to other types of dynamic loadings including blast loading and wave-slamming. Such loadings are typically highly transient and the structural and material response occurs over very short (dynamic) time scales of the order of milliseconds or microseconds. In addition to mechanical loading, composite structures are subjected to severe hygrothermal conditions which compromise their mechanical response.
