Delamination in short is a state where the layers of GRP material held in a resin matrix become separated from one another. Delamination can also apply to joinery where plywood normally due to moisture will separate about the bonded sheets. Delamination may also apply to where GRP layers loose bonding with underlying core materials such as foam or balsa.
