Abstract
An advanced composite structural component, made of a poller and wood fiber composite material, in the form of an extruded or injection molded thermoplastic member in residential and commercial structures. 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 components have u…
