Abstract:
1. A method for manufacturing a structural assembly with an integral damping system, the method comprising: positioning a first portion of fiber-reinforced resin material against a first tool surface to at least partially form a stiffener having a first end portion opposite a second end portion; positioning a layer of damping material against the first portion of fiber-reinforced resin material, the layer of damping material extending from the first end portion of the stiffener to the second end portion of the stiffener; positioning a second portion of fiber-reinforced resin material against a second tool surface offset from the first tool surface to at least partially form a skin; positioning a third portion of fiber-reinforced resin material against the layer of damping material to laminate the damping material between the first and third portions of fiber-reinforced resin material, the third portion of fiber-reinforced resin material extending from the first end portion of the stiffener to the second end portion of the stiffener; and cocuring the first, second and third portions of fiber-reinforced resin material to bond the stiffener to the skin.
