Abstract
Provided are adhesive articles and related methods of making and use. The adhesive article includes one or more patterned adhesive layers comprising compositionally and spatially distinct adhesives that are laterally disposed relative to each other. The first and second adhesives are optionally capable of being functionally cured to provide a structural adhesive bond with a substrate. These adhesives can provide high fracture toughness and high modulus characteristics not otherwise possible in a homogeneous adhesive composition. These adhesives can provide some degree of crack arrestment and significantly reduce the need for mechanical fasteners in industrial bonding applications.
