Because of its light weight, corrosion resistance, high temperature resistance, and high strength, it has been widely used in various fields such as aerospace, marine development, ships, ships, and high-speed rail cars in recent years, and has replaced many traditional materials.
At present, glass fiber and carbon fiber composite materials play a huge role in the fields of offshore energy development, shipbuilding, and marine engineering repair.
Application in ships
The first application of composite materials on ships began in the mid-1960s and was first used to make deckhouses on patrol gunboats. In the 1970s, the superstructure of mine hunting boats also began to use composite materials. In the 1990s, composite materials have been fully applied to the ship’s fully enclosed mast and sensor system (AEM/S). Compared with traditional shipbuilding materials, composite materials have good mechanical properties. When used in the manufacture of ship hulls, they have the characteristics of lighter weight and more energy saving, and the manufacturing process is relatively simple. The application of composite materials on ships not only achieves weight reduction, but also increases radar and infrared stealth functions.
The United States, Britain, Russia, Sweden, France and other navies attach great importance to the application of composite materials in ships and have formulated corresponding advanced technology development plans for composite materials.
High-strength glass fiber has the characteristics of high tensile strength, high elastic modulus, good impact resistance, good chemical stability, good fatigue resistance, and high temperature resistance. It can be used to make deep-water mine shells, bullet-proof armor, lifeboats, high-pressure vessels and propellers Wait. The U.S. Navy has used composite materials for the superstructure of ships very early, and the number of ships equipped with composite superstructures is also the largest.
The composite superstructure of the US Navy ship was originally used for minesweepers. It is an all-glass steel structure. It is the largest all-glass composite minesweeper in the world. It has high toughness and no brittle fracture characteristics. It has the ability to withstand the impact of underwater explosions. Excellent performance.
2. Carbon fiber
The application of carbon fiber reinforced composite masts on ships has gradually emerged. The entire Swedish Navy’s corvettes are made of composite materials, achieving high-performance stealth capabilities and reducing weight by 30%. The entire “Visby” ship has an extremely low magnetic field, which can evade most radars and advanced sonar systems (including thermal imaging), achieving a stealth effect. It has the special functions of weight reduction, radar and infrared dual stealth.
Carbon fiber composite materials can also be applied to other aspects of ships. For example, it can be used as a propeller and propulsion shafting in the propulsion system to reduce the vibration effect and noise of the hull, and it is mostly used in reconnaissance ships and fast cruise ships. In machinery and equipment, it can be used as a rudder, some special mechanical devices and piping systems, etc. In addition, high-strength carbon fiber ropes are also widely used in naval warship cables and other military items.
Carbon fiber composite materials have other applications on ships, such as propellers and propulsion shafts on propulsion systems, which are characterized by reducing the vibration and noise of the hull, and are mostly used in reconnaissance ships and fast cruise ships, special mechanical devices and Piping system, etc.
Civil yacht
The superyacht brig, the hull and deck are covered with carbon fiber/epoxy resin, the hull is 60m long, but the total weight is only 210t. The carbon fiber catamarans built in Poland use vinyl ester resin sandwich composite materials, PVC foam and carbon fiber composite materials. The mast booms are all customized carbon fiber composite materials. Only part of the hull is made of glass fiber reinforced plastic. The weight is only 45t and has a speed. Fast, low fuel consumption and other characteristics.
In addition, carbon fiber materials can be used in yacht instrument dials and antennas, rudders, and reinforced structures such as decks, cabins, and bulkheads.
Generally speaking, the application of carbon fiber in the marine field started relatively late. In the future, with the development of composite technology, the development of maritime military and the development of marine resources, as well as the enhancement of equipment design capabilities, the development of carbon fiber and its composite materials will be promoted. Flourish.
