Composite aircraft structures suffer from more complex damage modes than traditional metals. Many investigations tend to look into specific aspects of composite damage mechanisms but seldom take a more systematic view. This paper introduces a new fault tree analysis to capture information on damage modes of composite structures by identifying damage sources and process defects. Minimal cut sets are calculated based on the construction of the fault tree. Qualitative analysis is then performed incorporating Structure Importance Analysis, Probability Importance Analysis and Relative Probability Importance Analysis to determine the main damage modes and sources. Some potential solutions are proposed accordingly to improve the reliability of composite structures
