In 2026, with the establishment of the national “Low-Altitude Economy Development Administration” and the rapid rollout of regional industrial policies, China’s low-altitude economy has fully transitioned from conceptual exploration to a fast track of large-scale, commercial development. In this industrial revolution that is reshaping how we utilize airspace, one fundamental yet critical factor determines the performance limits and commercial viability of aerial vehicles: advanced composite materials. These materials not only serve as the engineering cornerstone for reducing aircraft weight and enhancing efficiency, but also act as the core driving force behind the safe and efficient development of the entire industry ecosystem—quietly shaping the form and rules of future three-dimensional transportation. A transportation and industrial revolution led by drones and electric vertical takeoff and landing (eVTOL) aircraft is now poised to unfold in the low-altitude domain.

Low-altitude aircraft are driven by an uncompromising pursuit of performance: longer endurance, greater payload capacity, enhanced safety, and lower operating costs. At the heart of all this lies a single, fundamental engineering challenge. — Lightweighting. Composite materials, with their exceptionally high specific strength and specific modulus—particularly carbon-fiber composites—have emerged as the “ultimate solution” to this challenge.

Compared with traditional aluminum alloys, carbon fiber composites can achieve A structural weight reduction of 20% to 40%. For the Rainbow-9 UAV, designed for an endurance of up to 40 hours, and the Jiutian UAV, with a range of 7,000 kilometers, every gram of weight saved translates directly into longer loiter times or a larger payload capacity. In both the consumer and industrial drone markets, the extensive use of composite materials is the fundamental enabler that allows these platforms to flexibly perform missions such as inspection, logistics, and crop protection.

I. From From “emerging industry” to “pillar industry”: a powerful boost for the materials sector

In 2026, the development of China’s low-altitude economy reached a milestone policy inflection point. For the first time, the Two Sessions explicitly designated the low-altitude economy as an emerging pillar industry on par with integrated circuits, aerospace, and biopharmaceuticals, signifying a strategic elevation from a “new growth engine” to a critical component of the national economic structure. This upgrade in top-level design implies that fiscal, land, airspace, and financial resources will be allocated to this sector across the board and with high priority.

of the policy system The “four beams and eight pillars” framework is set to take shape at an accelerated pace in 2026. The “Guidance on Building the Low-Altitude Economy Standards System (2025 Edition),” jointly issued by ten departments including the State Administration for Market Regulation, has mapped out a clear roadmap for the standardized development of the entire industry chain, including airworthiness certification for composite materials. The newly revised Civil Aviation Law of the People’s Republic of China will come into effect on July 1, 2026, providing legal safeguards for low-altitude flight operations and facilitating a shift in airspace management from a “permit-based” system to “precision-based management.” Approval timelines are expected to be compressed from weeks to hours, thereby unlocking substantial potential for commercial operations. Meanwhile, five departments, including the Ministry of Industry and Information Technology, have jointly issued the “Opinions on Strengthening Capacity Building in the Information and Communications Industry to Support the Development of Low-Altitude Infrastructure,” mandating that by 2027 nationwide coverage of ground mobile communication networks along public low-altitude air routes reach at least 90%, thus establishing a robust “digital skyway” for low-altitude flight. In addition, the National Development and Reform Commission and two other departments are promoting the establishment of a mandatory liability insurance regime for unmanned aerial vehicles, effectively fastening the “seatbelt” for the safe and healthy development of the industry.

These intensive and far-reaching policy incentives have created unprecedentedly stable demand for the upstream composite materials industry. Since 2021, China’s low-altitude economy has entered a phase of rapid development, presenting new opportunities for industrial growth. According to data released by the National Development and Reform Commission, the market size of China’s low-altitude economy reached RMB 505.95 billion in 2023 and is projected to reach RMB 1.5 trillion by 2025, with further expansion beyond RMB 1 trillion expected in 2026 and potentially reaching RMB 3.5 trillion by 2035. Moreover, production-driven development is clearly the dominant trend: looking solely at the value-chain distribution within the UAV industry, upstream and midstream segments—including raw materials, components, and complete-system manufacturing—account for 70% of total output value. Local governments have also rolled out supporting measures, such as equipment-purchase subsidies and additional tax deductions for R&D expenses, for material companies that meet airworthiness certification requirements, thereby directly reducing firms’ innovation costs and accelerating the localization and large-scale production of aviation-grade composite materials.

II. From Material Innovation to Scenario Implementation

Currently, the application of composite materials in the low-altitude economy is rapidly advancing along three key dimensions: innovation in material systems, upgrading of manufacturing processes, and deepening of application scenarios.

1. Concurrent Advancement of High-Performance Material Systems and Multifunctionalization

Under the trend of carbon fiber leading high-end manufacturing, High-strength, high-modulus T800 and T1100 carbon fibers have now achieved domestic mass production and have become the core materials for eVTOL airframes and the primary load-bearing structures of UAVs. Guangwei Composite’s carbon fibers and prepregs have been included in COMAC’s procurement catalog and the company has secured a major RMB 658 million order in the aerospace sector, underscoring its competitive edge in high-end aviation applications.

Thermoplastic composites ( Thermoplastic composites (TPCs) offer advantages over conventional thermosetting materials, including recyclability, rapid molding, and excellent impact resistance, making them pivotal for future large-scale manufacturing. At the 2025 Paris Air Show, Airbus prominently showcased TPC components, underscoring their substantial potential in next-generation aircraft.

Composite materials are no longer limited to structural applications; they have also become functional and intelligent. Through modification or specialized design, they can be endowed with additional functionalities, such as electromagnetic shielding to meet the communication requirements of complex environments and the realization of stealth capabilities.

2. Digital and Automated Manufacturing: Ushering in the “First Year of Mass Production”

Faced with explosively growing market demand, composite materials manufacturing itself is undergoing a profound intelligent and digital transformation, aimed at achieving high-performance, low-cost, large-scale, and stable production in order to meet The “year of mass production” for eVTOLs has arrived. Automated manufacturing processes have broken through the bottlenecks hindering large-scale production; traditional hand-layup and bagging techniques can no longer meet future demands. As a result, automated fiber placement (AFP) and automated tape laying (ATL), filament winding, and robot-based flexible assembly systems have become the industry mainstream. In today’s era, where digital twins are driving the integration of design and manufacturing, building a “digital twin factory” to conduct end-to-end simulation and optimization of production workflows, equipment layout, and supply chains in a virtual environment enables proactive identification and mitigation of mass-production risks and costs, while significantly shortening the R&D cycle. This “predictive manufacturing” model is the inevitable choice for addressing the rapid iteration and customization needs of eVTOLs and other similar products.

3. Comprehensive Empowerment of the Flight Platform

From high-end military platforms to civilian logistics drones, composite materials are the undisputed workhorse. The widespread use of carbon fiber, glass fiber, and other composites in drone fuselages, wings, and rotor blades is key to achieving long endurance, high maneuverability, and heavy payload capacity. eVTOLs and urban air mobility (UAM) represent the fastest-growing segment for composite-material demand, with each eVTOL incorporating 60% to 70% composites by weight—far exceeding the share in conventional airliners. Models such as Peak Aviation’s “Kerry” and EHang Intelligent’s EH216-S extensively utilize carbon-fiber composites in their airframes to achieve both lightweight construction and high structural strength. Leading international companies like Archer and Vertical Aerospace have also established long-term partnerships with top-tier material suppliers, including SGL Carbon, to ensure a stable supply of advanced composites. Composites likewise excel in infrastructure and support systems, including lightweight, high-strength drone takeoff-and-landing platforms, weather-resistant communication radomes, and high-pressure hydrogen storage vessel liners for hydrogen storage and transportation systems.

III. Opportunities and Challenges for Chinese Materials

China boasts the world’s most complete composite materials industrial chain and has achieved breakthroughs in key materials such as carbon fiber, starting from A breakthrough from “catching up” to “running alongside.” The rise of the low-altitude economy has opened a fast track for leading companies such as Zhongfu Shenying, Guangwei Composite Materials, and Hengshen Shares to enter high-end aerospace applications, enabling them to move from being “alternative suppliers” to becoming “primary suppliers.”

However, the path to the global industry’s pinnacle remains fraught with challenges: on the one hand, the airworthiness certification system for aerospace materials is complex, time-consuming, and costly, posing a significant barrier for many small and medium-sized enterprises. With the implementation of the “Guidance on Building a Standards System for the Low-Altitude Economy,” relevant material standards will gradually be clarified; yet companies will still need to allocate substantial resources to validation efforts. On the other hand, while pursuing higher performance, the key to large-scale application lies in leveraging process innovation to continuously reduce manufacturing costs. At present, policy incentives for the first-of-its-kind equipment and R&D subsidies are helping firms overcome this challenge. Moreover, the development of thermoplastic composites, bio-based composites, and efficient recycling technologies will become both a social responsibility and a technological imperative for the industry’s long-term, sustainable growth.

In summary, the low-altitude economy did not emerge out of thin air; rather, it is the product of a policy-driven blueprint, the trailblazing advances in technology, and the synergistic ties among industries. Among these, composite materials stand out as the most robust and lightweight. “Invisible Wings.” From the strategic direction set at the national level to the call of a trillion-dollar market, from fiber tow bundles in the laboratory to aircraft soaring through the skies, this quiet materials revolution is the foundation that turns low-altitude aspirations into reality. Looking ahead, as 2026 marks the “inaugural year of routine operations,” with continuous advancements in materials science and an increasingly mature manufacturing ecosystem, composite materials will undoubtedly step forward in smarter, greener, and more cost-effective forms—providing deep, multifaceted support for a three-dimensional China where every industry and every sector takes flight.
