Probabilistic design methodology is the focus of this discussion of the reliability assessment of advanced composite structures. The traditional deterministic design methodology commonly used in the aerospace industry is reviewed in terms of safety factors that represent uncertainties in the design procedure. Then, the probabilistic design methodology is introduced as a candidate that has the potential to assess the quantitative reliability of advanced composite structures and enhance the performance and the reliability of composite structures. Probabilistic design methodology is applied to fuel tanks as an example of an aerospace composite structure. A comparison is made of the design internal pressures of fuel tanks evaluated by deterministic and probabilistic design methodologies. Finally, the applicability of the probabilistic design methodology is discussed.
