The present disclosure relates to vehicle component materials. More specifically, the present disclosure relates to environmentally-friendly materials for vehicle dashboards and other vehicle components.
Conventional vehicles, for example automotive vehicles, generally have interior components and paneling made from synthetic materials in order to meet numerous governmental regulations for safety and reliability. However, many of these conventional interior components are discarded once the vehicle reaches the end of its lifespan. These conventional interior components increase landfill waste and a vehicle's carbon footprint.
For purposes of summarizing the disclosure and the advantages achieved over the prior art, certain objects and advantages of the disclosure are described herein. Not all such objects or advantages may be achieved in any particular embodiment. Thus, for example, those skilled in the art will recognize that the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other objects or advantages as may be taught or suggested herein.
All of these embodiments are intended to be within the scope of the invention herein disclosed. These and other embodiments will become readily apparent to those skilled in the art from the following detailed description of the preferred embodiments having reference to the attached figures, the invention not being limited to any particular preferred embodiment(s) disclosed.
In one aspect, a vehicle having an interior panel is described, wherein the interior panel comprises a recycled material, and wherein the recycled material comprises a recycled base material and a resin.

Embodiments of the present disclosure and their advantages are best understood by referring to the detailed description that follows. It should be appreciated that like reference numerals are used to identify like elements illustrated in one or more of the figures, wherein showings therein are for purposes of illustrating embodiments of the present disclosure and not for purposes of limiting the same.
The present disclosure may be understood by reference to the following detailed description. It is noted that, for purposes of illustrative clarity, certain elements in various drawings may not be drawn to scale, may be represented schematically or conceptually, or otherwise may not correspond exactly to certain physical configurations of embodiments.
Embodiments relate to vehicle components and interiors panels (e.g. such as a vehicle dashboard) that can be made from sustainable, recyclable, recycled, biodegradable, compostable, and otherwise environmentally friendly materials. Many environmentally-friendly materials have not conventionally been implemented in previous vehicle components because they have been too weak to provide for the rigorous demands of vehicular applications. For example, large temperature variations, high vibration, high humidity, exposure to ultraviolet (UV) light, flammability issues, and exposure to other external environmental conditions, including continuous passenger wear and tear, have caused premature failure of many vehicle components made from nontraditional materials. Stringent government specifications for safety and reliability have prevented some environmentally-friendly materials from being implemented within vehicle applications.
Embodiments of the interior panels, such as a vehicle dashboard may be made from recyclable, recycled, sustainable, biodegradable, compostable and/or otherwise environmentally friendly materials. In one embodiment, these panels have similar or the same strength, durability and reliability of interior panels made from less environmentally friendly plastics or metals. It will be understood that the materials herein may be implemented in vehicle components other than dashboards, such as side door panels, rear window panels or other vehicle components. Increasing the use of environmentally-friendly materials within the components of a vehicle may decrease the environmental impact of the vehicle, for example, by reducing landfill waste and the vehicle's carbon footprint. Using environmentally friendly materials for components in a vehicle can be beneficial, particularly, for example, within electric vehicles.
The interior panel (e.g. dashboard) can include a sustainable, recyclable, recycled, biodegradable, compostable and otherwise environmentally friendly material. A “recyclable material” is a material wherein at least a portion of the material is capable of being reused and/or recycled. A “recycled material” is a material wherein at least a portion of the material was made from a recyclable material that has been reused and/or recycled. In some embodiments, the material of the interior panel (e.g. recycled material) comprises a base material (e.g. recycled base material). In some embodiments, the base material can include a sustainable, recyclable, recycled, biodegradable, compostable and otherwise environmentally friendly material. In some embodiments, the material of the interior panel (e.g. recycled material) comprises a resin (e.g. bio-based resin). In some embodiments, the resin can include a bio-based, sustainable, recyclable, recycled, biodegradable, compostable and otherwise environmentally friendly resin. In some embodiments, the resin includes a non-recycled (i.e. prime or virgin) and/or non-recyclable resin. In some embodiments, the interior panel comprises a material, wherein the material comprises a base material and a resin. In some embodiments, the interior panel comprises a recycled material, wherein the recycled material comprises a recycled base material and a resin. In some embodiments, the interior panel comprises a recycled material, wherein the recycled material comprises a recycled base material and a bio-based resin. In some embodiments, the recycled material is recyclable, biodegradable, compostable and otherwise environmentally friendly material. It is to be understood that the interior panel can be made of a material comprising various combinations of the materials described herein, with or without other materials. In some embodiments, the interior panel can include one or more recycled or recyclable materials.
In some embodiments, the recycled material is a top most layer of the interior panel. In some embodiments, the interior panel further comprises a substrate material disposed under the recycled material. In some embodiments, the substrate material provides structural support to the interior panel and/or the recycled material. In some embodiments, the substrate material includes a plastic material. In some embodiments, the recycled material is self-supporting, and does not require a support structure in order to hold its form. In some embodiments, the interior panel comprises a film disposed over the recycled material. In some embodiments, the interior panel does not comprise a film disposed over the recycled material. In some embodiments, the interior panel further comprises a tear seam. In some embodiments, the tear seam is configured to tear due to the force caused by a deployed airbag.
