LOW-COST ROUTES TO THE MANUFACTURE OF COMPLEX SHAPED COMPOSITE PARTS HAVE BEEN DEFINED USING METAL FORMING TECHNIQUES AND DU PONT'S LONG DISCONTINUOUS FIBER (LDF) TECHNOLOGY. THESE MANUFACTURING TECHNIQUES INCLUDE ROLL FORMING, STRETCH FORMING, AND PRESS FORMING. NEAR EQUIVALENCE BETWEEN THE STATIC, DYNAMIC, AND DAMAGE TOLERANCE PROPERTIES OF LDF AND CONTINUOUS FIBER COMPOSITES HAVE BEEN DEMONSTRATED. SEVERAL EXAMPLES ARE CITED WHICH DEMONSTRATE THE POTENTIAL FOR THIS TECHNOLOGY TO SIGNIFICANTLY REDUCE THE COST OF AEROSPACE COMPONENTS.
