Carbon fiber is often hailed as the “King of New Materials” and “black gold.” As its applications continue to expand, drones—as high-tech products—have also begun to incorporate carbon fiber, which is primarily used in drone casings and components.
Looking at the history of drone development, flight endurance has long been constrained by the need to increase energy capacity while maintaining a given energy density—essentially, achieving longer flight times within a limited energy supply. However, providing more space for energy storage not only enables higher speeds but also significantly extends flight range. Carbon fiber is an excellent material for weight reduction. With a density of only 60% that of traditional lightweight materials like aluminum alloy, it effectively achieves structural lightweighting.
In addition to its light weight, carbon fiber offers outstanding strength, toughness, and weather resistance. These properties effectively protect the airframe from damage caused by drops and enhance its impact resistance—all of which are critical requirements for drone airframe materials. As a non-metallic material, carbon fiber has low electrochemical activity and excellent corrosion and aging resistance, effectively extending the service life of drones.
