The blades made of carbon fiber are not only lighter and thinner, but also can improve cavitation performance, reduce vibration and underwater characteristics, and reduce fuel consumption. This has made significant progress in improving the propeller blades of ships. Like Carbon Fiber Tube And Rod and Carbon Fiber Sheet And Cnc.
In addition, stealth is also an important index to evaluate the progressiveness level of military ships. Improving stealth performance requires reducing the radar reflection cross-section of the ship's hull and lowering its optical characteristics. In the past, multiple whip and strip shaped antenna masts were erected on the superstructure of ships, which greatly hindered their stealth ability in detection equipment.
Nowadays, ships use carbon fiber composite materials, which are lightweight, high-strength, corrosion-resistant, and have excellent stealth capabilities.
The proportion of carbon fiber is less than 1/4 of that of steel, but its hardness is 8-9 times that of steel, and it can also deform freely. The tensile strength of carbon fiber resin composite materials is generally above 3.5Gpa, which is 7-9 times that of steel, and the tensile elastic modulus is 2.3-4.3Gpa, which is also higher than that of steel.
