The environmental degradation of various types of honeycomb core sandwich constructions was investigated. The constructions included combinations of aluminum and plastic core materials with aluminium, graphite composite, and fiberglass composite skins and various types of adhesives. The objectives of the investigation were to assess (1) the degree of improvement in durability of new, corrosions resistant aluminum over the untreated type, (2) the significance of the adhesive on interfacial durability, (3) possible adverse galvanic corrosion of aluminum honeycomb bonded to graphite composite skins, and (4) comparative durability of aluminum versus plastic honeycomb. Analysis of the results established the significance of environmental degradation upon the various skin/core/adhesive combinations and assessed the existence and extent of synergistic interactions between the various structural constituents and the environmental factors.
