Low-density foam core sandwich composite find an increasing use as structural materials. They are often used for high performance structural applications such as in the hull forms of racing yachts, patrol crafts, lifeboats and catamaran ferries. There is a growing emphasis on selecting different materials and their behavior under flexural loading. In addition, fracture mechanics analyses of low-density foam core have been performed by several authors [
