Abstract
In accordance with one embodiment of the present invention, the invention comprises a continuous structural composite preform wet out system and method which takes as an input pre-formed structural composite structures with a structural foam core, passes these structures through a wetting system which may comprise sprayers, brushes, a die or dies, or other wetting means; applies a cure process such as ultraviolet light, heat, curing agent or other cure method, and produces a completed, cured structural composite structure such as a beam or panel for use in any structure as desired by the user. The improved structural composite wet out system of the invention provides run rate, ease of use, structure efficiency and handling advantages over the pultrusion systems of the prior art by achieving higher production rates, the ability to use light cure resins and the ability to produce composite structures of non-uniform cross-section.
