As automotive vehicle frame can be strengthened by reinforcing the tubular frame elements that form the side door openings. A three dimensional core element and rigid foam can be incorporated into each tubular frame element to achieve a significant increase in the frame bending strength, without adding appreciable weight to the vehicle frame.

1. An automotive vehicle framing system comprising:a tubular side frame defining a door opening; said side frame comprising a hollow sill forming a lower edge of the side frame; a three dimensional core extending longitudinally within said hollow sill; and rigid polymer foam extending within said sill to reinforce the sill against bending loads, the rigid polymer foam extending between an inner surface of the sill and the core, wherein said core includes a midsection; a forward side surface tapered from the core midsection to a front end, and a rearward side surface tapered from the core midsection to a rear end.
