MANUFACTURING DAMPED RESONATOR ACOUSTICAL PANEL |
摘要 |
A method of manufacturing a damped resonator acoustical panel in which a porous acoustical damping fabric and a resin impregnated open weave fabric are laid up and subjected to moulding by the application of heat and pressure thereto to cause a portion of the resin from the open weave fabric to impregnate the abutting portions of the acoustical damping fabric and bond the fabrics together. A film of an adhesive is then applied to the open weave fabric and heated by a hot gas stream until it reticulates. The bonded fabrics are then bonded to the edges of an open honeycomb core by means of the reticulated adhesive. A solid sheet is bonded to the other side of the honeycomb core in order to close the cells thereof. |
