Across a wide array of structures and platforms ranging from temporary facilities to the most advanced aircraft, various layered materials address the need for high strength and stiffness at low weight. Most commonly in fiber composites, these materials involve fiber reinforced face sheets and a foam, honeycomb or balsa wood core sandwich construction. While a range of commercial products are available to meet many specific performance requirements, significant limitations exist in the use of commercial core materials. Foster-Miller, Rutgers University and Weidlinger Associates have joined to develop, produce and market a new approach to layered structure design which exploits advanced geometry algorithms recently developed at Rutgers. The proposed program benefits greatly from the major commitment of these three organizations to this effort and the larger market goals. The overall concept enables low-cost production of an array of multidimensional core materials for different applications. Since the forms are defined by the Rutgers geometry algorithms, they can be analyzed and optimized with mating structural codes proposed by Foster-Miller. Initial comparative data will be generated to demonstrate the validity of the concept and facilitate rapid movement toward Phase II full-scale evaluation and application. (p00627) The proposed program will develop modeling procedures and initial data for an entirely new class of layered composite core materials. The inherently easy to produce materials will have widespread application to systems ranging from advanced aircraft to low cost civil structures. Blast protection barricades are currently the top non-military target application.
