ABSTRACT:
A manufacturing method for producing a unitized composite material has been discovered. An assembly of loose fibers or fiber and fabric combinations is formed where at least one of the layered elements contains a bondable material such as a thermally sensitive bonding fiber. The un-bonded layered assembly is shaped into a wavy form having a repeating wave-like pattern of the desired amplitude and wavelength. The amplitude and wavelength of the repeating waves can be altered such as by changing the relative speeds of a transfer device and an oven wire and the height of the transfer device relative to the height of the oven wire using simple machinery control settings. The shaped assembly is subsequently bonded in an oven or other activation step preserving the wave-like shaping when cooled or removed from the activation effect.
