Vehicle bonnet constructions for reducing impact forces
The technology relates to vehicle panels. The vehicle panel may comprise a top layer and a bottom layer. The top and bottom layers may be bonded together. The bond of the top and bottom layer may be a weld. One or more energy absorbing layers may be positioned between the top layer and the bottom layer. The one or more energy absorbing layers may be comprised of one or more energy absorbing materials. The energy absorbing layers may be aluminum honeycomb and polyurethane foam.
1. A vehicle panel comprising:
a top layer including one or more cutouts; and
a bottom layer,
wherein the bottom layer is bonded to the top layer, and
wherein either the top layer or the bottom layer includes a plurality of individual forms attached to a surface of at least one of the top layer or the bottom layer and the plurality of individual forms are provided between the top and bottom layers.
2. The vehicle panel of claim 1 , wherein the plurality of individual forms each have different sizes.
3. The vehicle panel of claim 1 , wherein each of the individual forms comprises a square form or a rectangular form.
4. The vehicle panel of claim 1 , wherein the one or more cutouts have different sizes.
5. The vehicle panel of claim 1 , wherein the plurality of individual forms are each coated with an adhesive.
6. The vehicle of claim 5 wherein the plurality of individual forms coated with the adhesive bonds the top layer and bottom layer together.
