Abstract
A laminate comprising a first ply, a second ply, and a plurality of interfacial modifiers arranged between opposing faces of the first ply and the second ply. A chemical composition of an interfacial modifier of the plurality of interfacial modifiers can be selected based on a resulting bond strength between the interfacial modifier of the plurality of interfacial modifiers and at least one of the first ply or the second ply. The plurality of interfacial modifiers can be arranged in a pattern to selectively modify toughness of a portion of the laminate based on the bond strength of the interfacial modifier of the plurality of interfacial modifiers.
