Abstract
A sound absorption panel in which a honeycomb core exhibiting cell end planes has bonded to those planes a porous fiberglass pelt, a layer of thermoplastic material intermediate the core and the porous fiberglass pelt having been subjected to pressure and heated to the point of liquification providing the bond between the porous fiberglass pelt and the cell end plane of the honeycomb core. The thermoplastic in its melted state penetrates the fibers of the porous fiberglass pelt and flows around the edges of the cell end plane of the honeycomb core.
