Benefits of technology
[0008] Advantages of the present invention include fiber-reinforced composites having improved thermal stability, improved resistance to fire, improved flexibility and strength, reduced density, and reduced emission of volatile organic compounds (VOCs) during manufacturing.
Problems solved by technology
Still, conventional wooden building structures such as doors, wall panels, and windows, while aesthetically pleasing, may suffer from some disadvantages.
For example, solid wood doors can experience significant shrinking and swelling in response to extremes of temperature and humidity.
Also, there is a tendency for doors and door frames to be bumped by objects being transported through the doorway.

[0173] The following examples describe particular embodiments of fiber-reinforced composites of the present invention and particular embodiments of methods and systems of the present invention.
[0174] Fiberglass Reinforced Polyurethane Panels Door Skins
[0175] In an embodiment, the fiber-reinforced composite of the present invention is a door skin or a panel such as may be used for a wall or door unit. In an embodiment, the door skin or panel comprises lips that can at least partially wrap around the frame of the structure to be covered. For example, the lips may wrap around the rails and / or stiles used to make the door frame. The lips may be sized to completely overlap one another. Alternatively, the door skin or panel may be flat with square edges.
[0176] Door skins having six panels such as that shown in FIG. 1 were made with the fiber-reinforced composite of the present invention. Thus, as shown for the door skin of FIG. 1, in an embodiment, the door skins of the present inventi...
