In sandwich structure engineering, a core material is the low-density central layer bonded between two thin, high-strength “face sheets” (skins). Its primary mechanical function is resisting out-of-plane shear stress and preventing the skins from buckling. Unlike a solid thick plate, which would be heavy and expensive, the core acts as a spacer to increase the section modulus (stiffness) while adding minimal weight. This is analogous to an I-beam, where the vertical web is the “core” separating the top and bottom flanges.
