     PROCESSING AND APPLICATION OF POLYMER MATRIX COMPOSITE MATERIALS

			Dr. Lisa C. Veitch
	The Institute for Defense Analyses, Alexandria, VA  22311

     Polymer matrix composite (PMC) materials have been used in 
  commercial and military systems since the 1940s.  Over the years, 
  composite materials have found their way into a variety of markets 
  including boats, general aviation, vehicles, infrastructure and 
  recreational equipment. Usage of these materials, however,  has 
  been limited in the commercial and military aviation industry because 
  of high costs to manufacture composite parts, the lack of computer 
  models that can predict failures in composites and limited non-destructive 
  inspection and repair techniques. This presentation will explain the basic 
  properties of PMCs and  how these composite materials are produced.  Both 
  traditional and the latest state-of-the-art composite processes will be 
  discussed as well as current uses of PMCs.  Finally, reasons why composites  
  are not used more extensively in the aircraft industry  and what is needed 
  to overcome  shortfalls related to manufacturing and modeling composite 
  properties will be presented.
