With the development of aerospace technology, the demand for high-performance materials is becoming increasingly urgent. Hollow glass microspheres, as a lightweight and high-strength filling material, are becoming a new favorite in aerospace. This new type of material has brought revolutionary innovation to the aerospace industry due to its unique performance and wide application.

Hollow glass microspheres are filled with gas inside, with a particle size generally ranging from ten to several hundred micrometers. This type of microsphere has an extremely low density, but its strength and compressive performance are excellent. Due to its lightweight and high-strength characteristics, hollow glass microspheres have shown enormous potential for aerospace applications.

Hollow glass microspheres are widely used to manufacture aircraft components in aircraft manufacturing. The durability and rigidity of composite materials can be significantly enhanced by integrating lightweight glass microspheres, resulting in a reduction in their total weight at the same time. This lightweight and high-strength material helps reduce aircraft fuel consumption, improve operational efficiency, and improve environmental performance.

The use of hollow glass microspheres in the construction of satellite structures has garnered significant interest, aside from their application in the production of aircraft. Satellite structures need high strength, lightweight, and stable characteristics to ensure normal operation in extreme environments. Hollow glass microspheres, as an ideal filling material, can meet these strict requirements and provide guarantees for the stable operation of satellites.
