Research Topics


W. Brandt Goldsworthy & Associates, Inc. (WBG & AI) proposes to extend and demonstrate a pultrusion technology package, for advanced composite materials, that offers a better product with improved performance and at a lower cost than competing technologies. The significance of this technology for reducing the weight and the cost of high performance Navy hardware, and commercial products has independently been evaluated by Boeing. The Phase II objective is to develop the pultrusion technology into a manufacturing demonstration of flight hardware. It specifically concerns two structural parts of a lifting body that is currently in the R & D stage at Boeing.It is expected that the Phase II program will prove significant innovations in design for pultrusion, pultrusion-injection-die design, new fiber architecture development, and joining technology. The pultruded flight hardware will be delivered for component testing at the conclusion of the basic Phase II program. Due to the continuous nature of the pultrusion process, multiple components will be available at the end of the basic Phase II program.WBG & AI proposes to subsequently excercise the Phase II option in order to assemble the pultruded hardware into a full size lifting body section, in which all the structural load paths are now present. This structure will be delivered for testing to Boeing.
