Layered hybrid matrices for carbon fiber reinforced composites

Polymeric composites have gone through a level of maturity beyond the laboratory stage with the development of all composite aircraft the Boeing 787. Yet the basic understanding of the material used in its primary structure has not been extensively investigated. Although this may be attributed in part to the proprietary nature of the system, we believe that it is because of lack of specific tools required for its analysis. Specifically, micromechanical models always assume an evenly distributed homogeneous matrix while lamination theory assumes constant stress through the laminate thickness. Our program now in its second year at the Polymeric Composites Laboratory formerly at the University of Washington and now part of independent organizations in Seattle supported by industry as well government agencies and in collaboration with several universities on a global scale is developing such a foundation for matrices in layered configurations. Specifically, this work focuses on the development of model systems that can be studied without concerns of proprietary and/or export control requirements.
