The low-altitude economy, an emerging and comprehensive economic model, is flourishing at an astonishing pace, becoming a new engine driving socio-economic progress. It extensively encompasses key sectors such as aviation manufacturing, air transportation, aviation tourism, and aviation training, with the manufacturing and application of drones being a pivotal aspect of this economic form. In this context, new composite materials, particularly carbon fiber composites, are playing a crucial role in the low-altitude industry due to their exceptional properties of being lightweight, high-strength, corrosion-resistant, and high-temperature resistant, injecting robust momentum into the industry's sustained prosperity.
An overview of new composite materials reveals that they are innovative materials achieved through advanced material preparation technologies, which involve the combination and optimization of materials with different properties. These materials complement each other, resulting in products that boast multiple advantages such as being lightweight, high-strength, corrosion-resistant, and wear-resistant. Among these, carbon fiber reinforced plastics (CFRP) stand out as a paragon of new composite materials. CFRP is ingeniously composed of carbon fibers and a resin matrix, where the carbon fibers bear the external forces, and the resin matrix serves to fix the fibers, maintain the shape, and transfer external forces. This unique combination endows CFRP with mechanical properties that far surpass those of traditional metallic materials, leading to its widespread application in various fields including aerospace, automotive manufacturing, and construction.
