Abstract
A steering column having a composite steering column support housing formed from a fiber reinforced matrix material. By layering the fibers within the matrix material of the support housing to a specific orientation, controlling fiber length, and controlling fiber and polymer type, the performance of the steering column can be manipulated to optimize NVH, structural stiffness, load path, crash energy management, mass balance, and cost. The column support housing contains at least one mounting hole for coupling to either an instrument panel or engine compartment wall. The column support housing may have a protruding region for stabilizing the steering column to the instrument panel when the support housing is mounted to the engine compartment wall. The mounting hole can also contain an elastomeric washer or a filler material for improving dampening characteristics, and further may have a circular fiber orientation immediately surrounding the mounting hole to further improve performance characteristics.
