The production and manufacturing of carbon fiber reinforced series materials consists of three core links: carbon fiber precursor preparation, carbonization treatment, and composite molding. Technological breakthroughs in each link drive industrial iteration. In the precursor preparation stage, traditional polyacrylonitrile (PAN) - based precursors have problems of uneven strength and high impurity content. The new polymerization process, by precisely controlling the monomer ratio (acrylonitrile to comonomer ratio of 92:8) and spinning speed (1500 meters per minute), increases the precursor strength to over 8GPa and reduces the impurity content to below 0.1%, laying a high - quality foundation for subsequent carbonization. The continuous transformation of the carbonization link has achieved remarkable results. The adoption of a three - stage carbonization furnace (pre - oxidation furnace at 200 - 300℃, low - temperature carbonization furnace at 400 - 800℃, and high - temperature carbonization furnace at 1200 - 1500℃) to replace traditional batch - type equipment shortens the carbonization cycle from 8 hours to 2.5 hours. Moreover, the fluctuation of carbon fiber modulus is controlled within ±5GPa, greatly improving product stability.

The diversified development of composite molding technologies meets the needs of different scenarios. The autoclave molding process is suitable for high - end components in aerospace and other fields. Through the synergistic effect of 0.5 - 0.8MPa pressure and 120 - 180℃ temperature, the fiber volume fraction of the material reaches 60% - 65%, and the mechanical properties of the products are uniform. The pultrusion molding process realizes large - scale production. For long strip products such as pipes and profiles, it can achieve a molding speed of 1 - 2 meters per minute, and the straightness error of the products is less than 0.1mm/m. The winding molding process is used in the manufacturing of high - pressure vessels. By precisely controlling the winding angle (adjustable from 15° to 90°) and tension (50 - 200N), the compressive strength of the vessel is 3 times higher than that of metal materials, and the weight is reduced by 40%. In addition, the popularization of automated molding equipment (such as robotic fiber placement systems) increases production efficiency by 30% and reduces labor costs by 25%, promoting the transformation of carbon fiber reinforced materials from "niche and high - end" to "available to the general public".

In the application field, the performance advantages of carbon fiber reinforced series materials continue to be released. The aerospace field is still the core application scenario. This material is used in components such as fuselage structures and engine blades, which can reduce the weight of the aircraft by 20% - 30% and improve fuel efficiency by more than 15%. At present, the carbon fiber consumption of mainstream civil airliners has accounted for 15% - 20% of the fuselage weight. The demand in the new energy vehicle field has shown explosive growth. The carbon fiber reinforced materials used in battery pack casings and chassis frames can meet the requirements of impact resistance and corrosion prevention, while reducing the vehicle weight by 100 - 150kg and increasing the cruising range by 50 - 80 kilometers. The carbon fiber consumption per vehicle of global automakers is breaking through from 5kg to 20kg. In the high - end equipment field, this material is used in wind turbine blades (with a length of more than 60 meters), which can improve the fatigue resistance of the blades, extend the service life to more than 20 years, and the weight reduction increases the power generation efficiency of the wind turbine by 8% - 10%. The innovative application in the construction field is also gradually expanding. It is used in the reinforcement of long - span bridges and anti - seismic components of high - rise buildings. Its tensile strength is 7 - 10 times that of ordinary steel bars, and its corrosion resistance can reduce later maintenance costs.

From the perspective of industrial development, the global carbon fiber reinforced material market is in a period of rapid expansion. The global market size has reached 12 billion US dollars in 2024 and is expected to exceed 25 billion US dollars by 2029, with a compound annual growth rate of over 16%. At the policy level, many countries have included it in the category of strategic new materials. For example, China's "14th Five - Year Plan for the Development of the New Material Industry" clearly proposes to "expand the application scale of high - performance carbon fiber composite materials", and the European Union supports the alternative application of carbon fiber in the aviation field through the "Clean Aviation Program". At the same time, the challenges faced by the industry are gradually being solved: the cost of precursor production has decreased by 40% through large - scale production, and the recycling technology (such as chemical depolymerization) has achieved a carbon fiber recycling rate of over 90%, solving the problem of resource waste. In the future, with the continuous maturity of technology and the expansion of application scenarios, carbon fiber reinforced series materials will become a key support for promoting high - end manufacturing and green transformation.
