ABSTRACT:
BACKGROUND OF THE INVENTION
Various structural members such as beams are subjected to point loaded forces. Examples of such members are a center reinforcement for a door beam or an automotive or vehicle bumper or similar beam. In order to maximize the load requirements it is desirable to reinforce such beams. It is also desirable to minimize the weight requirements and resultant costs without sacrifice to performance.
SUMMARY OF THE INVENTION
An object of this invention is to provide a center laminate reinforcement for a structural beam.
A further object of this invention is to provide techniques for reinforcing beams by optimizing the reinforcement materials.
In accordance with this invention techniques are provided which are particularly adaptable to structural members in the form of elongated beams which might be subjected to being point loaded and thus having a bending moment diagram that is triangular or generally parabolic in shape. Such beam is provided with a reinforcement layer made of a polymer material which forms a structural foam in its cured condition. A characteristic of the polymer layer is that its edges are tapered toward each other in a direction away from the location of the point loading.
In a preferred practice of this invention the polymer layer is initially coated on a carrier which is then inserted as a drop in insert between spaced side walls of the channel shaped beam. Upon curing the polymer layer becomes intimately bonded to both the carrier and the side walls of the beam.
The beams could be of various cross-sectional shapes such as U-shape, C-shape, angle-shape, L-shape and could be single or multi-celled.
