Mechanical Strength in Sandwich Panels

One of the most important factors in the preference for sandwich panels in structures is their load-bearing capacity. The loads that structures face consist of various factors such as self-weight, wind load, snow load, and temperature. These factors can affect the structure either individually or in combination. Especially in large and wide structures, the mechanical strength of sandwich panels plays a critical role.

Sandwich panels have a composite structure thanks to internal fillings such as polyurethane or rock wool between two metal surfaces. This composite structure increases the panels' load-bearing capacities. However, it is important to accurately assess the behavior of the panels under the loads they are subjected to. External factors such as wind, snow, and temperature can significantly affect the strength of the panel.

Importance of Composite Structure

The composite structure of sandwich panels provides superior mechanical strength even when each layer may be weak independently. For example, metal surfaces with a low elasticity modulus and internal filling materials may struggle to carry their own weight alone. However, in composite form, these materials work together, providing high shear and bending resistance, thus forming a stronger structure. This significantly enhances the panel's overall load-bearing capacity.

Trapezoidal Shape and Core Material Strength

Another factor that increases the mechanical strength of sandwich panels is the trapezoidal shape and the strength of the core material. The trapezoidal shape is a structure that enhances the panel's load-bearing capacity. Additionally, core materials such as polyurethane or rock wool increase the panel's durability, minimizing deformation even under heavy loads. This improves the panel's resistance to external factors and ensures structural safety.

Load-Bearing Capacity of Sandwich Panels

When evaluating the load-bearing capacity of sandwich panels, not only the thickness of the metal surfaces but also the type and quality of the core material play a critical role. Rock wool-filled panels provide superior performance in terms of fire resistance and mechanical strength, while polyurethane-filled panels stand out with their high thermal insulation properties.
