摘要： A conjugate damper for a structural panel includes a constraining sheet extending between a first edge and a second edge. Each of the first edge and the second edge is at least partially coupled to a first surface of the structural panel. The conjugate damper also includes a damping layer coupled between the constraining sheet and the first surface such that, when the structural panel is in a compressively deformed state, a thickness of the damping layer in a direction generally normal to the first surface is decreased relative to a baseline state. The damping layer includes a viscoelastic material.

摘要： An acoustic barrier structure can include a support structure that defines a plurality of cells, a weight attached to the support structure, and at least one resonant membrane covering one of the plurality of cells. The at least one resonant membrane can comprise at least one weight. The at least one resonant membrane can have an anti-resonant frequency and the support structure with the weight can provide wide frequency band gaps between odd resonance modes while suppressing structure-membrane coupled modes to enable the anti-resonance of the at least one resonant membrane.

摘要： Systems and methods for reducing noise in aircraft fuselages and other structures are described herein. A noise reduction system configured in accordance with one embodiment of the invention includes an auxetic core, a damping layer, and a constraining layer. In this embodiment, the auxetic core is supported by a structural member, and the damping layer is sandwiched between the auxetic core and the constraining layer. A method for manufacturing a structural assembly in accordance with another embodiment of the invention includes forming a stiffener by positioning a first ply of composite material against a first tool surface, positioning damping material against the first ply, and positioning a second ply of composite material against the damping material to sandwich the damping material between the first and second plies. The method can further include forming a skin by positioning a third ply of composite material against a second tool surface offset from the first tool surface, and attaching the stiffener to the skin by co-curing the first, second and third plies of composite material.

摘要： The present teachings generally relate to an acoustic panel including a backing layer, honeycomb core attached to the backing layer, a mesh layer attached to the honeycomb core, and a face sheet including a flexible acoustic fabric face sheet attached to the mesh layer. The acoustic fabric face sheet can provide improved sound dampening characteristics over, for example, a perforated face sheet, and at a lower manufacturing cost, weight, and a simplified manufacturing process. The acoustic fabric face sheet can be or include a flexible woven and/or knitted fabric including a polymer such as an aromatic polyamide that includes a meta-aramid fiber, or a fiberglass fabric.
