摘要：
A layer of non-metallic open weave fabric sandwiched between the perforate sheet and an outer thin sheet of microporous fabric of a broad band noise attenuation panel comprising a cellular core adhesively bonded between a pair of metal facing sheets, one perforate and the other imperforate in order to provide enhanced durability in a severe environment. The microporous fabric is constructed from a metal different from at least the perforated sheet and is adhered to the perforated sheet. A method of manufacture of such panel is disclosed.
