Abstract
In-line systems and in-line methods are described that can be used to provide lightweight reinforced thermoplastic composite articles that include a textured film layer. The textured film layer can provide one or more of water resistance, flame retardancy, a desired surface roughness or other desired properties. The lightweight reinforced thermoplastic composite articles that include a textured film layer can be used in building applications, in recreational vehicle applications and in other applications as desired.
Claims20
An in-line process of producing a thermoplastic composite article using an in-line system, the in-line process comprising:
- combining reinforcing materials and a thermoplastic material in an aqueous solution;
- disposing the aqueous solution with the combined reinforcing materials and the thermoplastic material onto a moving support;
- removing water from the disposed aqueous solution on the moving support to form a porous web comprising open cell structures formed from the reinforcing materials and the thermoplastic material;
- drying the porous web on the moving support to provide a porous core layer;
- heating the dried, porous core layer on the moving support to melt the thermoplastic material of the heated, porous core layer;
- disposing a first textured film layer on a first surface of the heated, porous core layer on the moving support;
- and
- applying pressure to the heated, porous core layer comprising the disposed first textured film layer on the moving support to provide a thermoplastic composite article and retain texture of the first textured film layer on the thermoplastic composite article.
