ABSTRACT

Assembly of the skins and the core is achieved by bonding with adhesives or directly with the resin impregnating the bers of the skins. In some exceptional cases, the skins are welded on the core. ”e bonding quality is of course fundamental to obtain the best performance and durability of the sandwich part. In general,

0.025 mm ≤ adhesive thickness ≤ 0.2 mm

4.2 Simpli™ed Flexure 4.2.1 Stress In Figure 4.3, we highlight in a simplied manner the main stresses that arise when a sandwich beam is subject to bending.* ”e beam is clamped at its left end and subjected to a transverse load T at its right end. We isolate an elementary slice dx of the sandwich beam and we magnify the deformation. ”us, we can observe on any cross section ashear stress resultant Tand amoment resultant M according to the classical notations of strength of materials.
