Application Of Carbon Fiber Composite Material In Argo Buoy Shell

Argo buoys, also known as self-submerged buoy profile detection buoys, are dedicated to the measurement of ocean subsurface temperature, salt, and deep profiles. The Argo buoy is in a free drifting state in the water. After deployment, it will automatically dive into the specified depth. After reaching the predetermined time, it will automatically rise to the surface of the water. During the climbing process, profile measurement of temperature, salinity and other data will be performed.
The National Ocean Technology Center, in conjunction with the international Argo plan, promotes the advancement of domestic profile buoy technology, towards the development of multi-element measurement, large depth (dive depth less than 4000 meters) and the improvement of the level of craft materials, and the improvement of the technology of domestic profile buoys Horizontally, carbon fiber composite material is one of the excellent compression materials with deeper buoy depth.
The Argo buoy is composed of three parts, a cylindrical long tube in the middle, and the upper and lower end caps are hemispherical. Since the shell is immersed in seawater for a long time, the corrosion resistance and pressure resistance must be excellent. Carbon fiber has such advantages. The carbon fiber composite material buoy shell has the characteristics of low density and light weight. The quality is lighter than that of aluminum metal, which is only about 1/4 of that of steel. It can provide more space for the buoy and can be loaded with more detection instruments; The carbon fiber composite material buoy shell has the characteristics of corrosion resistance and strong creep resistance. It is resistant to the corrosion of acid, alkali, salt and atmospheric environment, does not require regular maintenance, and has a long service life.
Carbon fiber composite material buoy shell has the characteristics of high compressive strength. The strength of carbon fiber is extremely high, much higher than that of steel pipe, 6-12 times that of steel, and can reach more than 3000mpa, which can fully resist the static pressure of sea water and maintain the stability of the shell. With the full implementation of my country's Argo plan, a large number of various types of profile buoys will be launched, and carbon fiber composite materials will be more and more used in buoy shells due to their excellent characteristics.
