Abstract

A method of making an aircraft acoustic structural panel () begins with preforming a core honeycomb laminate () having preformed foam () bonded inside cells () thereof by a distinct adhesive (). The preformed honeycomb laminate () is then stacked between opposite top and bottom structural outer laminates (). The stacked honeycomb laminate () and outer structural laminates () are then compressed together under heat and pressure into a unitary structural panel () having the core honeycomb laminate () integrally bonded between outer skins (). The outer laminates () may include imperforate acoustic septums () bounding the core honeycomb laminate () followed by an outer honeycomb () and structural fiber layers () defining the outer skins ().
