Release time：2023-02-27 Views
With the development of technology, the exploration of unknown fields has gradually begun. Faced with high-risk, high-intensity tasks, unmanned operations have been utilized. Originally developed for military purposes, drones were used for reconnaissance and target practice. Due to the increasing demand for civilian use, drones have been introduced into the civil market for aerial photography, surveying, crop protection, disaster relief, transportation, and more. As various industries continue to explore the applications of drones, the requirements for their carrying capacity and performance are also becoming higher.

As a hot topic in the international aviation field, drones' future development is heading towards efficient, long-distance flights with high load capacities and low energy consumption. Like automotive lightweighting, weight reduction can only be achieved by minimizing structural weight. The reduction in structural weight relies on both advances in body structure and power system design and the support of new materials.
In addition to using foaming materials in the wing area, foaming materials can also be selected as the core material for sandwich structures in the fuselage. When under bending loads, there is a certain distance between the upper and lower panels of the structure which can obtain a greater proportion of rigidity. This structure can significantly reduce weight while maintaining mechanical performance, and most importantly, it lowers costs.
When selecting sandwich materials, it is best to ensure lightweighting while being easy to process and having better mechanical performance. The PET foam material has application advantages such as excellent mechanical and mechanical properties, easy processing, environmental friendliness and recyclability, creep resistance, ease of coloring, and high temperature color stability.
Since drones are small and light, the fuselage mainly uses PET foam core material, effectively reducing the weight of the drone's body and greatly enhancing its endurance. Due to the excellent comprehensive performance of PET foam material, it is also applied to other parts of drones such as wings and tails.
As countries around the world increase their emphasis on the development of drones and investment in their production, the development of drones has entered a new era, and their future application needs will become more diverse. The application of foaming materials has played a vital role in the lightweight, miniaturization, and high-performance of drone structures. Compared with wood materials and composite materials such as carbon fiber and glass fiber, foaming materials have lower costs and stronger practicality, promoting the innovation of drone materials.
