USE OF THIN PLY COMPOSITES OFFERS GOOD POTENTIAL FOR SIGNIFICANT MASS SAVINGS FOR AEROSPACE STRUCTURES BESIDES ITS IMPROVED RESISTANCE TO MICRO-CRACKING, FATIGUE, AND DELAMINATION. HOWEVER, MASS SAVINGS DUE TO THIN-PLY TECHNOLOGY DEPENDS ON MATERIAL AND FABRICATION TECHNOLOGY, VEHICLE CONFIGURATION, STRUCTURAL DESIGN, LOADS ETC. STRUCTURAL INTEGRITY OF COMPONENTS MADE FROM THIN PLIES NEED TO BE CHARACTERIZED OVER THE SERVICE LIFE CONSIDERING THE OPERATIONAL AND ENVIRONMENTAL LOADS. ANALYSIS PACKAGES ARE THEREFORE NEEDED TO STUDY HOW THE THIN PLY MANUFACTURING PROCESS PARAMETERS, PART DESIGN AND FABRICATION AFFECT THE PROPERTIES AND PERFORMANCE OF THE COMPOSITE PART OVER THE SERVICE LIFE. TDA, THEREFORE, PROPOSES TO DEVELOP AN INTEGRATED ASSESSMENT TOOL FOR THIN-PLY COMPOSITES INCLUDING MANUFACTURING PROCESS, MATERIAL CHARACTERIZATION AND PERFORMANCE EVALUATION WHICH RESULTS IN IMPROVED DESIGN OF AEROSPACE STRUCTURES. OUR ANALYSIS METHODS AND TOOLS PROVIDE NASA AND OTHER INDUSTRY USERS TO EVALUATE, TEST NUMEROUS DIFFERENT CARBON MANUFACTURING TECHNOLOGIES IN ORDER TO COVER ALL REQUIREMENTS AS NEEDED.
