20120292805 | THIN-LAYER LIGNOCELLULOSE COMPOSITES AND METHODS OF MAKING THE SAME - In one aspect, the present invention is a thin-layer lignocellulose composite having increased resistance to moisture. The thin-layer lignocellulosic composite includes a mixture of no more than about 95% by weight of a lignocellulosic fiber and at least about 5% by weight of an organic isocyanate resin. The mixture further includes short fibers and a release agent that does not interfere with subsequent processing of the thin-layer lignocellulosic composite. The mixture is pressed between two dies at an elevated temperature and pressure and for a sufficient time to form a thin-layer composite of predetermined thickness, and to allow the isocyanate resin to interact with the lignocellulosic fiber and short fibers such that the resultant thin-layer composite has a predetermined resistance to moisture. | 11-22-2012 |

20090113830 | Composite garage doors and processes for making such doors - Metal doors may be more cost-efficient than wood to manufacture and maintain, but may not be as aesthetically pleasing to the consumer. For example, metal garage doors may only be available in limited color lines and often do not simulate a natural wood grain in a very realistic manner. Also, metal garage doors may be limited in design, in that it may be difficult to add three dimensional shaping, such as trim or paneling, to the outer surface of a metal door. For example, some manufacturers apply extrusive plastic panels to the face of a metal garage door to add a design to the face of the door. The plastic and metal components, however, may exhibit different physical properties in response to changes in temperature and humidity and thus, the door may exhibit warping or other types of deformation upon exposure to weather. | 05-07-2009 |
