Abstract
A laminate with improved substrate shape resemblance and moisture resistance may include a plurality of layers. The plurality of layers may be structured in various orders, or layups. Each layer of the plurality of layers may have a specific thickness, weight/areal density, and/or other features, such as orientation, relative to one or more of the other layers.
Claims22
A laminate for applying to a substrate surface, the laminate comprising:
- a plurality of layers, the plurality of layers comprising:
- a first resin layer comprising a first resin layer thickness and a first resin layer inner surface, wherein the first resin layer inner surface is located at a first resin layer distance from the substrate surface;
- a natural fiber layer comprising a natural fiber layer thickness and a natural fiber layer inner surface, wherein the natural fiber layer inner surface is located at a natural fiber layer distance from the substrate surface, and wherein the natural fiber layer distance is less than the first resin layer distance;
- and
- a second resin layer comprising a second resin layer thickness and a second resin layer inner surface, wherein the second resin layer inner surface is located at a second resin layer distance from the substrate surface, and wherein the second resin layer distance is less than the natural fiber layer distance;
- and
- wherein the plurality of layers define a top surface and an application surface,
- wherein the top surface is located at a top surface distance from the substrate surface,
- wherein the top surface distance is substantially uniform along the substrate surface and wherein the second resin layer is configured to help maintain the top surface distance substantially uniform along the substrate surface, and
- wherein the application surface is configured to be applied to the substrate surface.

A laminate for applying to a substrate surface, the laminate comprising:
- a plurality of layers, the plurality of layers comprising:
- a first resin layer comprising a bioplastic and first resin layer thickness;
- a natural fiber layer comprising a natural fiber layer thickness, wherein the natural fiber layer abuts the first resin layer;
- and
- a second resin layer comprising a bioplastic and second resin layer thickness, wherein the second resin layer abuts the natural fiber layer, and wherein the second resin layer thickness is less than the first resin layer thickness;
- a backing layer comprising a backing layer thickness, wherein the backing layer is a dry layer to allow for adhesion to a substrate;
- wherein the plurality of layers comprising the first resin layer, the natural fiber layer, the backing layer, and the second resin layer provide a substantially flat top surface.
