Core splice adhesive

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.

A thermosetting resin based on molecules containing epoxide groups, cured by reaction with a hardener such as an amine or anhydride. Valued for strong adhesion, low cure shrinkage, chemical resistance and high mechanical performance, it is widely used in structural adhesives, laminating resins, coatings and composite matrices.
