Lightweight panels used for boating or tralers

Sandwich panels are composed of relatively rigid outer layers sandwiching a softer inner core, and due to their substantial strength at very low weight they have become a possible substitute for traditional steel in a variety of boat panels applicatons. The way such materials behave when driven by resonating sources, such as the ship propulsion system, is crucial for understanding their suitability, and a very significant part of this vibration problem is the interaction of the vibrating material with the surround water. Sandwich panels are extensively used in modern engineering applications such as the marine and aerospace industries. Design tools to allow vascular networks to be incorporated into these structures will be essential for future applications. Sandwich panels are not a new concept and have huge potential for customisation and enhancement, which has special advantages. The two concrete skins were connected using steel reinforcement trusses to create a composite.

Sandwich panels are used in the floors, bulkheads, clean room panels and even the skin and wings. Sandwich panels are becoming more widely used for applications where high stiffness and strength as well as lightweight structures are needed. A common method of load introduction into sandwich panels is through inserts that are potted into the sandwich core. Sandwich panels are used in particular by the storage and food processing industries. Sandwich panels are the most important component in the construction of modern commercial refrigeration vehicles and trailer paneling. The use of these layered panels (sandwich) reduces production costs and gives better design flexability.
