ABSTRACT:
A means and method of enhancing the damage tolerance of adhesive bonds by introducing gaps in the adhesive to divide the adhesive layer into discrete regions. The gaps are created by placing strips of barrier material between the two adherends before the adhesive is put in place and cured. If the two adherends begin to debond along the interface between one of the adherends and the adhesive, the gap arrests the debonding process.
