Comments | Ecological composite materials in the new economy economy

■ Yi Xiaosu

Recently, the National Development and Reform Commission released the "Fourteenth Five -Year Plan" Biological Economic Development Plan, which will not only release the biological economic potential of up to 22 trillion yuan in 2025, but also to protect, develop and use biological resources to serve biological resources, serve the service, serve the service, and serve the service, and serve the service, serve the service, and serve the service and serve the service. Traditional industries such as agriculture, forestry, energy, environmental protection, and materials provide a new possibility of high -quality development and transformation and upgrading.

In the process of ecological environmental protection and scientific and technological development, there are often some embarrassing situations that care about each other, such as things that are violated, for example, to vigorously develop wind power for clean energy, but the wind and blades of composite materials must be used. Food, diversion network, etc., after using these consumables, it becomes annoying "white garbage". In fact, these disposable consumables are not only an indispensable auxiliary material in the process of wind power blades manufacturing, but also an aerospace military civilian aircraft, sea, land and air -tip composite material weapons equipment, various composite material sports and leisure equipment products, and glass reinforced reinforced club yacht yachts Rowing fishing vessels such as the manufacturing of color composite materials products must be used in the manufacturing of the product manufacturing. Among them, for some high -end products, these consumables even rely on imports.

In response to the garbage pollution of this disposable consumables, a feasible solution at this stage is material technology innovation, replacing traditional polymers and derivatives with new generation of green material products with biological source and degradable new generation of green material products, thereby leading the composite composite The green transformation and upgrading of material technology manufacturing technology and process consumable products.

It is understood that the newly established Jiangsu Province Carbon Fiber and Composite Materials Technology Innovation Center (the Yangtze River Delta Carbon Fiber and Composite Materials Technology Innovation Center) cooperated with the researchers of the Ningbo Noseto University Composite Materials Team, which made a breakthrough in this direction.

Taking the ventilation felt products as an example, the ecological air felt products they developed first aimed at the high-end aerospace market. In ECO-Compass, a large-scale international cooperation project supported by the Ministry of Industry and Information Technology and the EU government, it has the characteristics of Chinese resources and autonomy The ecological perforation of intellectual property rights is applied by the internationally renowned German Aerospace Research Center (DLR) application test. Its effect can meet the requirements of advanced composite material molding technology including aviation products. Bymented felt products, even surpassing the technical indicators of ace products in the international market.

Further research also found that this new type of ecological permeability can be reused several times, and after the service life of it as a process consumable, it can continue to be used as a lightweight functional filler. After the value of industrial application is over, it may be biodegradable, or it can burn additional thermal energy to achieve its use of items. All this is mainly from the biological attributes of this new material: from nature, return to nature, return to nature Essence

It is particularly rare that the main raw material for creating this ecological smelly foundation is jaoseki, and the planting of jaoseki can effectively prevent soil erosion, increase the organic matter content of soil, improve the activity of enzymes and microorganisms, and improve the quality of coastal salt soil. Effective biotechnology measures. In this way, the composite material industry manufacturing and agricultural hemp planting industry integrates together on a biological economy platform to achieve a win -win situation. Considering that the ventilation felt is a special -scale industry -specific consumables, it can be imagined that such new biological economy and new products are expected to become a model for future industrial and agricultural combination and the green transformation and upgrading of the composite material industry. Social benefits and economic benefits.

Such ecological new products are just an example of biological economic development and innovation. Another successful innovation is the thermosettic epoxy resin of biological source. This green epoxy resin can produce high -performance aerospace composite materials with carbon fiber composite. Essence With the support of the ECO-Compass project, such new materials have been applied research and evaluation with high-end customers such as AVIC, COMAC, Airbus and Germany and the German Aerospace Research Center, and the effect is also very encouraging.

The next development of biological economic composite material technology can consider the aggregation of biological polymer materials -solving two -way controllable technology and its application. The breakthrough of this technology will give it to the recycling of large products like wind power leaves to open up and open up a brand new one. Road, which is the predicament of unclean and unsuitable environment caused by the current wind power clean energy development.

As pointed out in the "Fourteenth Five -Year Plan" Biological Economy Development Plan, the characteristics of the biological economy are the new trend of "adhere to ecological priority" and develop a biomass substitution for green and low -carbon. Ecological countermethyls and diversion networks, biological source resins and their composite materials are a vivid case in this green development process, and it is also a successful portrayal of Chinese technology leading development.
