These New Energy Sources Cannot Do Without Carbon Fiber

 

Many studies at home and abroad have shown that carbon fiber reinforced composite materials can play the advantages of high elasticity and light weight in large wind turbine blades. The larger the external size of the blade, the more obvious this advantage is. Compared with glass fiber materials, the weight of blades made of carbon fiber composite materials can be reduced by at least 30%. The reduction in blade weight and the increase in stiffness are conducive to improving the aerodynamic performance of the blades, reducing the load on the tower and the axle, making the power output of the wind turbine more balanced and stable, and the energy output efficiency is higher.

 

If the conductivity of carbon fiber materials can be effectively utilized in structural design, damage to the blades caused by lightning strikes can be avoided. In addition, carbon fiber composite materials have good fatigue resistance, which is conducive to the long-term operation of wind blades under harsh climatic conditions.

 

 

 

Carbon Fiber + Lithium Battery

In the manufacturing of lithium batteries, a new trend has been formed, with carbon fiber composite rollers replacing traditional metal rollers on a large scale, with the orientation of “energy saving, emission reduction and quality improvement”. The application of new materials is conducive to increasing the added value of the industry and further improving the market competitiveness of products. At present, carbon fiber rollers have made a comprehensive breakthrough in the field of lithium battery manufacturing.

 

 

German manufacturer SGLCarbon and NIO have developed a prototype carbon fiber reinforced plastic (CFRP) battery housing for electric vehicles that is about 40% lighter than comparable aluminum housings.

 

It is reported that the use of composite materials, especially high-performance carbon fiber, in the battery housing system can enable the vehicle to achieve better dynamic performance and obtain a very high battery pack energy density (over 180 Wh/kg), thereby increasing the driving range.

 

 

Carbon Fiber + Photovoltaics

 

The high strength, high modulus, and low density of carbon fiber composite materials have also received corresponding attention in the photovoltaic industry, among which carbon-carbon composite materials are the most used in carbon-carbon thermal fields.

 

 

The application of some key components is also gradually advancing, such as the use of carbon fiber composite materials to make silicon wafer brackets, etc. Another example is the carbon fiber scraper. In the production of photovoltaic cells, the lighter the scraper, the easier it is to make it more precise, and good screen printing effects have a positive effect on improving the conversion effect of photovoltaic cells.

 

 

Carbon Fiber + Hydrogen Energy

 

The first batch of hydrogen energy commuter buses developed by Yutong Group and State Power Investment Hydrogen Energy Company for the 2022 Beijing Winter Olympics will serve the urban area of ​​Beijing. The three competition zones of Beijing Yanqing and Zhangjiakou use 165L hydrogen storage cylinders, which can be filled with hydrogen in 15 minutes. The designed cruising range can reach 630 kilometers, and it can go back and forth three times. It can also operate normally at a low temperature of minus 30 degrees.

 

This hydrogen energy car is all domestically produced and independent from materials, components to systems. The hydrogen-powered generator system, after the electrochemical reaction of hydrogen and oxygen, releases 100% pure water. Compared with traditional cars, the energy conversion rate of hydrogen energy batteries is as high as 60%-80%, which is 2-3 times that of internal combustion engines. Hydrogen is produced from wind power and photovoltaic renewable energy, taken from nature and returned to nature, truly achieving zero carbon emissions.
