A large proportion of current aerospace composite components are light sandwich structures that are susceptible to damage and are easily damaged. Because sandwich structure is a bonded construction and the face sheets are thin, damage to sandwich structure is usually repaired by bonding.

Facesheets of composite sandwich structures are made from multi-ply composite laminate and the most common type is the fibre-reinforced polymer laminates. Facesheet and core parts of the sandwich structure should be well integrated, so that structural integrity as well as functionality can be maintained over the life-time of the structure.

A sandwich structural element is essentially a composite construction, where a relatively thick core layer of low strength, stiffness and density is sandwiched between two thin, face layers of strong and dense materials Fig. 8.1.

Sandwich composite structures possess excellent flexural and shear properties. Their inherent lightweight characteristics make them ideal structural components where weight reduction is desirable [4]. Thus structural sandwich panels are

The repair section 30 may include a variety of different configurations and materials, depending on the structural needs and materials of the composite structure 20. For example, the face skin 22 ′ and covers 32 of the repair section 30 are made of the same material as the face skin 22 of the composite structure 20 e.g., a resin matrix with continuous woven fiber reinforcement, a metal, or ...
