Composite foam material sandwich structure core material
When designing high-temperature foam manufacturers, the main factors considered for the panel are the strength and stiffness of the material, and for the core material, the main factor considered is the maximum weight reduction. In aircraft structures, aluminum honeycomb or foam is usually used as the core material. With the advantages of high compressive modulus and light weight, they are widely used as core materials for aircraft structures and are often used with carbon / glass fiber prepregs. Common structures include wing leading edge, rudder, landing gear hatch, wing body and wing tip fairing. Although the honeycomb sandwich structure has outstanding advantages over the metal sheet metal structure, airlines are still actively looking for alternative materials because the honeycomb sandwich material requires high maintenance and repair costs during use. In some cases, if cracks and porosity occur in the panel, water and water vapor can easily enter the honeycomb. At low tempe...
