Composite materials

A composite material comprising:

• a first layer formed from a thermoformable reinforced thermoplastic composite including a polypropylene and a plurality of glass fibers dispersed within the polypropylene;
• wherein the thermoformable reinforced thermoplastic composite is consolidatable from an initial, lofted state having an initial thickness, to a substantially consolidated state having a final thickness that is less than the initial thickness;
• and
• a second layer fused to the first layer and formed from an expanded polypropylene foam;
• wherein the expanded polypropylene foam is compressible from an original form having an original average thickness to a compressed form having a final average thickness that is less than the original average thickness;
• wherein the second layer has a first region and a second region when the expanded polypropylene foam is disposed in the compressed form;
• wherein the first region has a first thickness that is less than the original average thickness, and the second region has a second thickness that is greater than the first thickness and less than the original average thickness;
• wherein the composite material is substantially free from an adhesive disposed between the first layer and the second layer;
• wherein the first layer has a basis weight of less than or equal to about 500 g/m2 when disposed in the substantially consolidated state;
• wherein the second layer has a basis weight of less than or equal to about 500 g/m2 when disposed in the compressed form;
• wherein a sum of the final thickness and the final average thickness is from about 5 mm to about 10 mm;
• and
• an attachment component formed from a polyolefin and bonded to the first layer.

A vehicle comprising:

• a body panel having an exterior surface, and an interior surface spaced opposite the exterior surface;
• and
• a composite material attached to the body panel and including:
• a first layer formed from a thermoformable reinforced thermoplastic composite including a thermoplastic resin and a plurality of fibers dispersed within the thermoplastic resin;
• wherein the thermoformable reinforced thermoplastic composite is consolidatable from an initial, lofted state having an initial thickness, to a substantially consolidated state having a final thickness that is less than the initial thickness;
• and
• a second layer fused to the first layer and formed from an expanded polyolefin foam;
• wherein the expanded polyolefin foam is compressible from an original form having an original average thickness to a compressed form having a final average thickness that is less than the original average thickness;
• wherein the second layer has a first region and a second region when the expanded polyolefin foam is disposed in the compressed form;
• wherein the first region has a first thickness that is less than the original average thickness, and the second region has a second thickness that is greater than the first thickness and less than the original average thickness;
• wherein the composite material is substantially free from an adhesive disposed between the first layer and the second layer.
