  • Enhanced composites via selective interfacial modification
    Patent number: 11148392
    Abstract: A laminate comprising a first ply, a second ply, and a third ply which sandwiching the second ply between the first ply and the third ply. The laminate further includes a first plurality of interfacial modifiers arranged between opposing faces of the first ply and the second ply. The first plurality of interfacial modifiers are arranged in a first pattern. The laminate includes a second plurality of interfacial modifiers arranged between opposing faces of the second ply and the third ply such that the first plurality of interfacial modifiers and the second plurality of interfacial modifiers are arranged on opposite faces of the second ply. The second plurality of interfacial modifiers are arranged in a second pattern. The first pattern and the second pattern are configured to increase crack growth resistance of the laminate by selectively toughening portions of the laminate to control propagation of interfacial cracks within the laminate.
