In the drone field, PMI foam material has become an ideal solution for key components of various drones by virtue of its core advantages of **lightweight, high rigidity, and harsh environment resistance**. The specific applications are as follows:

 I. Fuselage Components

The drone fuselage needs to reduce weight as much as possible while ensuring structural strength. The high specific strength of PMI foam can significantly reduce the fuselage weight (30%-50% lighter than traditional materials). Meanwhile, its uniform closed-cell structure can effectively improve the impact resistance and vibration resistance of the fuselage. Even in harsh field environments with high sand and humidity, it can avoid structural failure caused by material corrosion or deformation, ensuring the flight stability of drones in complex mission scenarios.

 II. Wing Assemblies

The wing is the core structure for drones to generate lift. The small and uniform cells of PMI foam can accurately optimize the aerodynamic shape and mechanical properties of the wing. In the resin liquid molding process, the material's excellent elongation at break enables the wing to maintain structural integrity when subjected to air flow loads. It not only improves the endurance of drones (lightweight reduces energy consumption) but also enhances their anti-interference ability in strong winds and turbulent environments. It is suitable for models with strict performance requirements, such as industrial inspection drones, civil drones, and special-purpose drones.

 III. Avionics System Packaging

The avionics equipment of drones has extremely high requirements for protection and lightweight. The closed-cell structure of PMI foam has good insulation and sealing properties, which can effectively isolate external electromagnetic interference and moisture erosion, ensuring the stable operation of electronic components. Meanwhile, its lightweight characteristic can reduce the impact of the avionics module on the drone's center of gravity, improving the accuracy of flight control. It is widely used in the avionics systems of surveying and mapping drones and agricultural plant protection drones.

In addition, the environmentally friendly feature of the material being completely halogen-free also meets the development needs of the drone industry for green manufacturing and safety compliance. It provides key support for the "lightweight, high performance, and high reliability" of drones from the material end, helping various drones achieve more efficient operational performance in fields such as logistics and distribution, geographical exploration, and security monitoring.
