Application Advantages Of Carbon Fiber Composite Materials in Ships And Underwater Pressure Components
In the past, carbon fiber composite materials were mainly used in the aerospace field. In recent years, this advanced composite material has also been gradually valued by the ship and underwater equipment manufacturing industry. This article introduces the application advantages of carbon fiber composite materials in ship hulls and underwater pressure components.
The application advantages of carbon fiber composite materials on the hull:
Compared with traditional shipbuilding materials, carbon fiber composite materials have unique performance advantages. First, carbon fiber composites have good mechanical properties. Using it to manufacture the hull is conducive to reducing the weight and thus reducing the fuel consumption. Under the premise of large-scale design and customization, the hull is relatively fast to build, and the construction and maintenance costs are much lower than steel hull materials. It is particularly important that the interface formed by carbon fiber and resin matrix can effectively prevent crack propagation and has good fatigue resistance. In addition, the chemical inertness of the surface of carbon fiber reflects corrosion resistance, which can effectively reduce hazards such as aquatic growth.
Carbon fiber composite materials have good wave and sound permeability, and are non-magnetic. The existing stealth warships are made of carbon fiber composite materials. The superstructure of the ship is made of carbon fiber composite materials. While reducing the weight of the hull, the frequency selection layer with filtering function can be embedded in the interlayer to transmit and receive electromagnetic waves at a predetermined frequency, thereby shielding the enemy's radar. electromagnetic waves.
In addition to the hull deck and superstructure, carbon fiber composite materials can also be used in other aspects of the ship. When used in the propellers and propulsion shafting of the propulsion system of reconnaissance ships and fast cruise ships, it can significantly reduce the vibration effect and noise of the hull. When applied to rudders, special mechanical devices and piping systems, the overall performance is far superior to traditional metal materials.
Application advantages of carbon fiber composite materials in underwater pressure components:
Because of its advantages of low density, high strength, high modulus, fatigue resistance, corrosion resistance and good designability, carbon fiber composite materials have been widely used in pressure components of various submersibles, deep-sea gliders and other equipment. .
In order to further meet the needs of different purposes such as military security, resource exploration, scientific exploration and commercial development in the marine field, high-performance lightweight marine equipment with long voyages, high speeds and even large diving depths has become the main development trend. Parts made of carbon fiber composite materials can fully meet the requirements of low weight, high strength, good pressure stability and become an ideal raw material for advanced marine equipment.
