Lamb Waves Propagation in Aluminum Honeycomb Structures

Honeycomb sandwich, formed by adhesively bonding metallic or non-metallic thin plates with honeycomb core, is one of the composites used extensively in the industry. The common types of honeycomb cores presently being produced are aramid fiber reinforced, glass fiber, and the metallic core such as titanium, corrosion resistant steel and aluminum. The facing materials are usually aluminum, fiberglass or carbon fibre laminates. With the core carrying the shear loads and skins carrying the bending load the honeycomb panel enjoys many applications in the aerospace industries and have been found in many structural components due to their extremely light weight, high stiffness and strength-to-weight ratio.
