Abstract
An advanced composite structural component, made of a polymer and wood fiber composite material, in the form of an extruded or injection molded thermoplastic member in residential and commercial structures is described. Preferably the structural component is used in a window or a door. Common window and door manufacture require the production of linear members with specifically designed cross-sectional shapes to form both the window frame structural elements and movable sash components. The structural elements must possess sufficient strength to permit the manufacture of a structurally sound window unit that can be readily installed into a rough opening and can cooperate with the wall structure to maintain structural integrity. The window or door should have sufficient strength to survive day-to-day use and abuse and to maintain window or door structural integrity after installation. The structural component has a hollow cross-section with at least one structural web and at least one fastener web formed within the component. The exterior of the extruded component is shaped and adapted for installation in a rough opening and to support window and door components. Such structural com…
