The analysis report of material selection for marine aluminum sheet
- 2017-03-05 10:04 -
Marine ship is one of the main tools of modern transportation. There are large marine ship, fishing boat, fishing boats and many types of inland vessels. At present, most of the ship material is the traditional steel plate, glass fiber reinforced plastic and aluminum sheet. The highest proportion of application is steel plate, followed by glass fiber reinforced plastic, and finally aluminum sheet. Marine aluminum sheet is a new type of ship material in recent years, but its performance is stable, corrosion resistance and corrosion resistance and durable, so the aluminum sheet market is also in a stable growth period.

In the selection of marine aluminum sheet, steel plate is the first choice, and is also the most widely used materials. From the strength point of view, the strongest is steel plate, followed by the aluminum plate. Glass fiber reinforced plastics, also known as glass fiber reinforced plastics, commonly known as FRP, that is, fiber reinforced plastic composite. From the point of view of safety factor, steel is most suitable for underwater hull. Because of the possibility of collision of large ships in the sea, the steel plate technology is more mature and more resistant to cracking. From the point of view of plasticity, FRP is better than aluminum sheet and steel plate. Generally small and medium-sized ships, if necessary, both beautiful and economical, then FRP is preferred. As for the ship with aluminum sheet, the most appropriate is used in some of the above high speed boat after all. Such as yachts, business ships, aluminum alloy sheet can effectively reduce the weight, improve the speed, and beautiful appearance, durable.
On the whole, these three kinds of shipbuilding materials have their own advantages and disadvantages, which can not be ignored in ship production. But from the national policy and the perspective of technology development, marine aluminum market will maintain steady growth, gradually replace part of the steel market, and become the mainstream of the future of ship materials.
