Abstract : A damage tolerant hybrid composite fuselage section has been designed, fabricated and tested. One of the key features of this structure is the integral crack arresters which have been incorporated into the design to increase its tolerance to damage, either inherent flaws or battle induced damage. The ability of the design to withstand critical flight loads has been demonstrated by both analysis and test. The effectiveness of the crack arresters, which are designed to stop a propagating crack (damage) and still allow the structure to carry limit load was roven in a series of tests where the completely analyzed using finite element techniques and shown to save both weight and cost over its metal counterpart. Analysis and testing of composite panels has also been done to investigate failure modes and establish design criteria for crack arrester designs.
