Abstract
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.
Claims26
A composite, comprising:
- a substrate that includes a glass material and a thermoplastic resin;
- a support layer disposed over the substrate, at least a portion of the support layer being in contact with the substrate;
- a thermoplastic layer disposed over the support layer, at least a portion of the thermoplastic layer being in contact with the support layer, and the thermoplastic layer consists of a majority of a thermoplastic material and optionally additives selected from the group consisting of ultraviolet inhibitors, thermal stabilizers, fire-resistant additives, pigments, silicones, stain resistance additives, wetting agents, anti-microbial agents, anti-gas fade agents, hydrophilic agents, hydrophobic agents, biodegradable additives, antioxidant additives, slip agents, anti-static additives, conductive particles, and semi-conductive particles;
- and
- a cover sheet disposed over the thermoplastic layer, wherein
- the thermoplastic layer is disposed between the substrate and the cover sheet, and
- the cover sheet includes polyester.
