A composite sheet material and method for forming the same is provided that includes a substrate, a matrix, and a cover sheet. The substrate has a first face surface, a second face surface, and a plurality of edges, and includes a thermoplastic material. The matrix is attached to the substrate. The matrix includes a support component having a first melting point, and a thermoplastic component having a second melting point. The second melting point is less than the first melting point. The cover sheet imparts one or more surface characteristics to the composite sheet material during thermo-pressure formation of the composite sheet material. |

1. A method of forming a composite sheet material, comprising:
forming a matrix that includes:
a support component selected from the group consisting of non-woven polyester, non-woven fiberglass, non-woven polyamide, and combinations thereof, anda thermoplastic component selected from the group consisting of polypropylene, polyethylene, polyamide and combinations and copolymers thereof, a melting point of the thermoplastic component being less than a melting point of the support component; andproviding a cover sheet including one or more polymeric materials selected from the group consisting of polyamide, polyester, polypropylene, polyethylene and combinations and co-polymers thereof that imparts one or more surface characteristics to the matrix during thermo-pressure formation; positioning the cover sheet on a side of the matrix that is opposite the side contiguous with the substrate; and subjecting the cover sheet to the thermo-pressure process during the laminating step. |
