What is a sandwich panel?
sandwich panel is a structural element consisting of thin outer layers of solid material held together together with a different material core in a similar way, because slices of bread form a sandwich around the filling. Weight, strength, durability and costs are factors in the selection of materials. Sandwich panels can provide greater strength and resist voltage with lighter weight than a single solid material. The strength of the unit largely depends on the strength of the adhesive link between the elements and the thickness of the core. These units can be designed for walls, roofs or buildings of buildings and are used in the aerospace industry. This type of board is a composite of wood springs associated with resin in a deliberate pattern. The skin is selected depending on where the prefab will be used. The cores are made of a wide range of materials. The core is often a widespread foam product such as polystyrene or polyurethane. Other cores include aluminum honeycomb and balsa wood. The sandwich panel can also be a treated polyurethane or mineralFiber like Nomex®, in the nucleus.
The design of the sandwich panel is to withstand considerable tension. When the panel bends, the skin on one side stretches and the skin on the other side is compressed. The core material that holds the unit together helps maintain the stiffness of the panel, which increases significantly with another thickness. Quality adhesive is essential for the integrity of panels, as it resists the tendency to slide in different directions when the Uni Unit is stressed.
Completed panels are tested on the ability of stress bearing, impact resistance and tensile and tensile strength. Testing also evaluates the tendency to peel off from the nucleus. The sandwich panel designed for air applications is tested to release fire and smoke and must meet strict standards.
Units produced for construction are sometimes referred to as structural insulating panels (SIP). Buildings built with SIP can be more airtight and better iZOLITATION THAN ASSEMBLY using standard frames construction. The main advantage of sandwich panels for the aerospace industry is to reduce the weight that is reflected in fuel savings. Structural units intended for use of aviation combine stability and strength with slight weight to improve the efficiency of the aircraft.
