Core crush

Compressive collapse of a sandwich core, occurring either in service under concentrated loads or as a manufacturing defect when autoclave or press pressure drives the core inwards, typically at chamfered panel edges. It leaves a dished or wrinkled panel and reduces the structure's load-carrying capability.

Honeycomb core

A core material formed from thin walls arranged into an array of hexagonal or similar cells, used on edge between face sheets so the cell walls carry compression and shear. It offers very high stiffness and strength for its weight, with common types made from aluminium foil, resin-coated aramid paper and thermoplastics.

Core shear

The shear loading carried by the core of a sandwich panel as it bends, transferring load between the two face sheets. Core shear strength and shear modulus are primary selection properties for core materials, and core shear failure is a common design-limiting mode in sandwich structures.

Skin-core debond

Loss of adhesion between a sandwich panel's face sheet and its core, arising from manufacturing defects, impact damage, moisture ingress or fatigue. It removes the shear connection the panel relies on and can grow under load, so debonds are a key target of non-destructive inspection.
