As we all know, carbon fiber composite materials have many excellent properties, such as lightweight, high strength, corrosion resistance, excellent mechanical properties, etc. It can replace traditional shipbuilding materials.
The first is the mechanical properties of carbon fiber. When used in the manufacture of ship hulls, it can make the ship lighter, lighter and have lower fuel consumption. The manufacturing process is relatively simple, easy to form, and the construction and maintenance costs are much lower than that of steel ships. At the same time, carbon fiber is excellent Excellent fatigue resistance, which can effectively prevent crack expansion; carbon fiber composite materials are corrosion-resistant and chemically inert on the surface, making it difficult for aquatic organisms to adhere to the surface of the ship. This is also one of the very important factors in selecting materials for ship construction. All of the above reasons have formed The unique advantages of carbon fiber composite materials in boat manufacturing.
Civilian vessel
Large yachts are generally privately owned, expensive, and require light weight, high strength, and good durability. Carbon fiber composite materials can be used in yacht instrument dials and antennas, rudders, and reinforced structures such as decks, cabins, and bulkheads. The proportion of carbon fiber composite materials used in today’s composite yachts has greatly increased, and some even use carbon fiber composite materials entirely. The superyacht “Panama” ketch built by Baltic Company has a hull and deck made of carbon fiber/epoxy resin. The hull is 60m long, but the total weight is only 210t, making it fast and low in fuel consumption. Features and excellent performance.
Military ship
Carbon fiber composite materials have good acoustic, magnetic and electrical properties, good wave and sound transmission, and are non-magnetic, so they can be used to improve the stealth performance of warships. The use of composite materials in the superstructure of the ship can not only reduce the weight of the hull, but also by embedding a frequency selective layer with filtering function in the mezzanine, it can emit and receive electromagnetic waves at a predetermined frequency, thereby shielding enemy radar electromagnetic waves. .
Take the “skiold” class cruiser built by the Norwegian Navy in 1999 as an example. The cruiser uses a sandwich composite material composed of a polyvinyl chloride foam core layer, glass fiber and carbon fiber interlayers. This design not only improves the strength-to-weight ratio , has good impact resistance, and also greatly enhances the characteristics of low magnetism, infrared resistance and radar scanning resistance.
Carbon fiber composite materials, with their excellent properties, have broad application prospects in the field of ships that have special requirements for material properties.
