composite sandwich structure

A composite sandwich structure is a type of engineered material made of three layers: two thin, strong outer sheets (faces) and a lightweight, thick middle core. The outer faces provide strength and rigidity, while the core keeps the layers apart, giving the overall structure a high strength-to-weight ratio. This design is commonly used in aircraft, ships, and building panels because it is lightweight yet very stiff and durable. The combination of materials allows for efficient support and resistance to bending, making the structure both strong and lightweight.
