Method for manufacturing secondary formed carbon fiber composite propeller
The present invention relates to a method for fabricating a carbon fiber composite propeller. And more particularly to a method for fabricating a secondary formed carbon fiber composite propeller.
Marine propellers have long been dominated by metal materials, with less consideration for the effects of materials on propeller performance. Metal materials have characteristics such as high hardness, small deformation, and high yield strength. Which they are reasons for long-term recognition. However, there are also many unfavorable factors, such as poor damping performance, large water noise, large weight. It is easy to cause vibration of the transmission shaft, prone to cavitation corrosion and induced fatigue cracks. Compared with traditional metal propellers, composite propellers. Especially carbon fiber composite propellers have high specific strength, large specific modulus, fatigue resistance, low vibration, low noise, lightweight, high efficiency, seawater corrosion resistance, easy maintenance, long service life, etc. Advantages, these have brought great potential to the future use of fiber reinforced composite propellers. Especially in the field of national defense and military applications. It is greatly improved the “stealth” performance of ships and was listed as a key development by many countries. Defense technology.
In foreign countries, composite propellers, especially carbon fiber composite propellers, have achieved initial success in application. In military applications, Italy’s black shark mine propeller, the US MK54 torpedo propeller, the German 206A submarine propeller, etc. are all made of carbon fiber reinforced composite materials. And they have reached a practical level; in civilian terms, the propeller made by Sweden Propulse AB has composed of one The metal hub and a number of replaceable composite blades are suitable for engines with a power of 20-300 hp. Once tested, the market has a good response. Composite propellers, especially carbon fiber composite propellers. They have been successfully assembled in superyachts or ships abroad, and the fuel consumption of propellers has been reduced by nearly 10%. But there is no mature composite propeller in China.
