What is balsa wood used for in sandwich structures?

In sandwich structures, balsa wood functions as the core layer that separates and supports the outer face sheets. Its primary role is to increase bending stiffness and load-bearing capacity without significantly adding weight. End-grain balsa is particularly effective because it offers high compressive and shear strength perpendicular to the panel surface. This makes balsa core materials ideal for hulls, decks, bulkheads, wind turbine blades, and structural panels requiring strength, impact resistance, and dimensional stability.
