Abstract
An improved composite for absorbing and dispersing impacting forces is disclosed. The composite includes a flexible plastic enclosure defining an internal cavity. The flexible enclosure is generally impermeable to air and capable of having its internal pressure changed. The composite further includes a foam core filling the cavity and retained within the cavity and adhered on substantially all of its external surface to the internal surface of the cavity. The cavity can be pressurized for higher impact absorbance. Methods for fabricating the composites are disclosed, as well.
