Abstract
An energy absorbing system has an inner tube and an outer tube that are stitched together. The inner tube contains a set of fibers oriented in a first direction and the outer tube has a second set of fibers oriented in a direction different from the first direction. Preferably these orientations are equal and opposite to each other. The inner tube may be hollow, but preferably has a cellular core. The outer tube may be spaced apart from the inner tube to create an annular cavity that is filled with a cellular material.
