CFRTP stands for Continuous Fiber-Reinforced Thermoplastics.

While prepreg stands for “pre-impregnated” to refer to composite materials made from fibers that have undergone the process of pre-impregnation.

Basically, prepregs materials are fibers (either carbon or glass) pre-impregnated using cured polymers matrix such as resin or epoxy.

The end result is a composite material whose characteristics provide the best performance and design flexibility.

Instead of having plastic, carbon fibers, or even steel as the primary component material, prepregs make up great (and highly effective) composite materials.

Advancing Aerospace: The Evolution and Challenges of Composite Materials in Aircraft Structures

The application of advanced composite materials in fighter aircraft is essential due to the high-performance requirements.

The emergence of advanced composite materials originated from the need for lightweight aircraft structures.

These structures demand high performance, comprehensive design, significant design complexity, and wide coverage, necessitating integrated optimization.

The design technology for these structures represents the direction of advanced composite material development.

Therefore, the application of composite materials in fighter aircraft structures represents the most advanced level of composite structural technology development.

The application of composite materials in aircraft structures can be roughly divided into three stages.

  • The 1st stage involves their use in carrying relatively simple components with minimal loads, such as various fairings, control surfaces, drag plates, landing gear doors, etc. These components can achieve weight reductions of approximately 20%.
  • The 2nd stage involves their application in high-load-bearing structures and primary structures, such as stabilizers, all-moving tails, forward fuselage sections, wings, etc., achieving weight reductions of 25% to 30%.
  • The 3rd stage involves their application in primary load-bearing and complex stress structures, such as fuselages, central wing boxes, etc., achieving weight reductions of 25% to 30%.

Application of Composite Materials in Military Aircraft

Advanced composite materials possess superior properties such as high specific strength, high specific stiffness, customizable performance, and ease of integral forming.

Utilizing them in aircraft structures can significantly reduce aircraft weight compared to conventional metallic structures while notably improving aerodynamic and elastic characteristics, thus enhancing aircraft performance.

The widespread application of advanced composite materials can further advance stealth and smart structural design technologies.

Therefore, the extent and quantity of advanced composite materials used in aircraft have become important indicators of structural advancement.

The usage of composite materials in helicopters has already reached 60% to 80% of the structural mass.

For instance, the RAH-66 helicopter from the United States utilizes composite materials for over 50% of its structural mass.

Moreover, the V-22 “Osprey,” capable of vertical takeoff, landing, and high-speed cruising, is nearly entirely composed of composite materials.

Application of Composite Materials in Civil Aircraft

Due to considerations of safety and economics, the application of composite materials in civil aircraft lags that in military aircraft.

Aircraft safety is the foundation of civil aircraft design criteria, while market competition drives aircraft companies to focus more on the overall life-cycle cost and performance benefits of aircraft.

The application status on aircraft such as Boeing 777 and Airbus A340 represents the current maturity level and application level of composite material technology in civil aircraft structures.

It is foreseeable that with the continuous accumulation and maturation of experience in using composite materials in military aircraft structures, as well as cost reductions, the application of composite materials will undoubtedly increase in the next generation of civil aircraft.

Development History of Composite Materials in China

China initiated research on composite materials and their application in aircraft structures in the late 1960s.

By the mid-1970s, the first composite aircraft component, an inlet wall panel for a certain fighter aircraft, was successfully developed.

In the 1980s, the application of composite materials transitioned from secondary load-bearing structures to primary load-bearing structures.

Components such as vertical stabilizers, horizontal tail wings, and forward fuselage sections have been used in various models in small-scale production.

This marked a new stage in the application of composite materials in aircraft structures in China, indicating the practical application of advanced aerospace composite materials.

Current Issues in China’s Composite Material Development

Industrial Development: Capacity versus Output

Compared with developed countries, the usage of composite materials in China’s military sector is relatively low.

In developed countries, composite materials account for over 50% of the usage in some military aircraft, while in China, the maximum usage in military fighter aircraft is less than 10%.

In civil aviation, the Boeing 787, for example, utilizes composite materials for over 50% of its structure, while China’s domestically developed regional jet ARJ only uses composite materials for 2% of its structure.

Although China has the capacity, the output still cannot meet the demand, and high-quality, high-performance fiber composite materials have not yet passed certification.

Contradiction between Structural Efficiency and Reliability

Among the scientific and technical challenges in the field of composite material research, the contradiction between material structural efficiency and reliability is the most difficult to resolve.

The variability in composite material performance and the uncertainty of service environments pose significant challenges, representing the Achilles’ heel of composite materials and structural engineering.

Weakness in Basic Research

The lack of basic research and the failure to achieve breakthroughs in key technologies hinder the development of the composite material industry.

The inherent characteristics of high input, high risk, and long research cycles in basic research are fundamental reasons for the weakness in China’s basic research on composite materials and the lack of original technological innovations.

By prioritizing basic research, promoting it through policies, and adhering to the integration of research, production, and application, China can overcome various challenges and promote the industrialization of composite materials.

Conclusion

After nearly 50 years of development, China’s composite materials have gradually formed a system, partly met the technical requirements of aircraft and helicopters, but still lagging behind developed countries overall.

The demand for new models provides new impetus and opportunities for advanced composite materials.

Therefore, with the advancement of material technology and aircraft development, advanced composite materials will be increasingly applied in aircraft and helicopters.
