For engineers working with composite sandwich constructions, one of the most critical decisions is selecting the right thickness. These panels feature dual outer layers with a low-density core in between, خرید کانکس providing high strength and stiffness while keeping weight low. They are widely adopted across industries demanding light yet robust structural elements. However, simply making the panel thicker does not always improve performance. The goal is to balance thickness against critical mechanical performance metrics.

The outer skins bear the majority of bending stresses. Increasing their thickness improves resistance to bending and reduces deflection under load. But the core plays an equally important role. Expanding the core height elevates the neutral axis separation, which significantly boosts the panel’s moment of inertia. Minor core thickening can yield disproportionate improvements in rigidity. However, if the core is too thick, it may become susceptible to core crushing or local buckling, especially if the core material is not strong enough to support the increased spacing.

The interplay between skin and core dimensions must be carefully managed. If the face sheets are too thin relative to the core, the panel can experience delamination under load. Conversely, if the face sheets are too thick and the core too thin, the panel may become unnecessarily heavy without significant gains in strength. The ideal configuration varies based on load conditions, whether it is point loads.

Material choice also influences the ideal thickness. For example, a foam core may require a greater dimension to prevent permanent deformation, while a aluminum honeycomb can maintain strength with a slimmer profile due to its high surface-to-volume ratio. Long-term environmental exposure alters mechanical properties, so thickness must be chosen to account for long-term performance, not just initial strength.

Advanced modeling tools allow precise prediction of panel behavior to predict performance under actual operational loads. Physical trials are critical for confirming analytical predictions. In practice, the most efficient sandwich panels are those where thickness is carefully calibrated—not over-engineered—to deliver the required strength with minimal material use. It cuts material, logistics, and energy costs while enhancing eco-efficiency.

True optimization balances performance, weight, and cost in equal measure. Success lies in intelligent design, not brute force.
