Explanation: With Reference to this excerpt from the Link it shows that it exactly means the splitting of the materials into thin layers as it is said to be a concern in aviation.
Delamination is an insidious kind of failure as it develops inside of the material, without being obvious on the surface, much like metal fatigue.
Due to increasing use of composite materials in aviation, delamination is increasingly an air safety concern, especially in the tail sections of the airplanes.

The FAA considers that, before structural failure, it may be possible to detect indications of possible failure modes that could result in separation of the vertical stabilizer from the airplane. These indications include edge delaminations, cracked paint, surface distortions, other surface damage, and failure of the transverse (side) load fittings. Similarly, indications of failure of the rudder assembly, which could lead to failure of the vertical stabilizer, may also be detectable with such an inspection. Although neither the FAA nor the NTSB have reached conclusions with respect to these possible failures on the accident airplane . . . . http://www.yachtsurvey.com/composite_troubles_in_aircraft.ht...

Many airplane parts are made of laminates nowadays. Please see my earlier question: http://www.proz.com/kudoz/1292404 and this useful reference http://download.r-g.de/fvw-einfuehrung.pdf

peeling
Explanation: as the joints are "bonded" this probably is done by means of a glue.
Delamination then indicates the bonding is not adhering anymore. See it as the glue which is peeling off the substrates (e.g glue on glass), or internal crack propagation in the glue itself (e.g. polyester on steel), or the ideal type (where the substrate breaks just below its surface)
Such delamination could be of adhesion or cohesion types. Difference is seen on the bonding surface.
