Abstract
Interior panels for motor vehicles and methods for making interior panels are provided. In one example, an interior panel includes, but is not limited to a fiber reinforced composite substrate that has a first side and a second side that is opposite the first side. The fiber reinforced composite substrate defines a plurality of inwardly tapered pockets. The inwardly tapered pockets are arranged proximate to each other and extend between the first and second sides. Each of the inwardly tapered pockets has an open end that is disposed in the second side and a closed end that is disposed adjacent to the first side.
Claims13
An interior panel for a motor vehicle comprising:
- a fiber reinforced composite substrate having a first side and a planar second side that is opposite the first side, wherein the fiber reinforced composite substrate defines a plurality of inwardly tapered pockets arranged proximate to each other and extending between the first and second sides, and wherein each of the inwardly tapered pockets has an open end that is disposed in the planar second side and a closed end that is disposed adjacent to the first side, wherein each of the inwardly tapered pockets is defined by inclined sidewalls that are formed in the fiber reinforced composite substrate extending from the open end and converging at the closed end such that the closed end is configured as a substantially pointed corner, wherein the inwardly tapered pockets each has a tapered profile and the first side that is directly opposite the open ends of the inwardly tapered pockets has a smooth profile that is spatially independent from the tapered profile;
- and
- a cover skin overlying the first side of the fiber reinforced composite substrate, wherein the cover skin comprises polypropylene, thermoplastic olefin (TPO), polyvinyl chloride (PVC), or a combination thereof.
A method for making interior panel for a motor vehicle, the method comprising the steps of:
- heating a fiber reinforced composite blank to form a heated fiber reinforced composite blank;
- compression molding the heated fiber reinforced composite blank to form a fiber reinforced composite substrate having a first side and a planar second side and defining a plurality of inwardly tapered pockets arranged proximate to each other and extending between the first and second sides, wherein each of the inwardly tapered pockets has an open end that is disposed in the planar second side and a closed end that is disposed adjacent to the first side, and wherein each of the inwardly tapered pockets is defined by inclined sidewalls that are formed in the fiber reinforced composite substrate extending from the open end and converging at the closed end such that the closed end is configured as a substantially pointed corner, and wherein the inwardly tapered pockets each has a tapered profile and the first side that is directly opposite the open ends of the inwardly tapered pockets has a smooth profile that is spatially independent from the tapered profile;
- and
- thermoforming a cover skin overlying the first side of the fiber reinforced composite substrate, wherein the cover skin comprises polypropylene, thermoplastic olefin (TPO), polyvinyl chloride (PVC), or a combination thereof.
