A honeycomb structure that includes cells in which septums are located to provide acoustic dampening. The cells are formed by at least four walls wherein at least two of the walls are substantially parallel to each other. The septums include warp fibers and weft fibers that are substantially perpendicular to each other. The septums are oriented in the honeycomb cells such that the weft fibers and/or warp fibers are substantially perpendicular to the parallel walls.
1. An acoustic structure that is adapted to be located near a source of noise, said acoustic structure comprising: a honeycomb comprising a first edge to be located nearest said source of noise and a second edge, said honeycomb further comprising a plurality of wall, said walls comprising an upper edge located at said first edge of said honeycomb and a lower edge located at said second edge of said honeycomb, said walls further comprising side edges that extend between said first and said second edges of said honeycomb, said walls being connected to each...
