Over the past several years, the use of advanced composites in high-speed boats for US Navy applications has been demonstrated in various platforms including the composite MAKO - delivered by Hodgdon Defense Composites in 2008. These applications show that advanced composite manufacturing, specifically closed mold infusion, have the potential to deliver boats that are stronger, lighter, inherently shock-absorbent, and more durable than conventional materials. Despite these initial demonstration successes, there are still barriers that need to be overcome before engineers can fully implement this new technology in the design, specification, and acquisition process for high-speed boats. The Project Team investigated three areas of research regarding the implementation of composite sandwich panels into naval hull designs. The three research areas investigated are: Evaluation of nondestructive testing techniques on foam cored sandwich panels Strain rate effects on polymeric foam cored laminates Impact resistance of foam cored sandwich panels with an interleaved layer.
