CRAG Working Group on Alternative/Equivalent Materials for Components Cleared Primarily by Structural Testing

Abstract

This report describes the conclusion and recommendations of the Composites Research Advisory Group (CRAG) working group on alternative equivalent materials for components cleared primarily by structural testing. The requirement for the Working Group arose from the identification that, due to insufficient understanding of composite behaviour, the introduction of an alternative material to a composite structure seldom occurred as extensive retesting is required. This clearly reduces the cost effectiveness of composite structures as the commercial advantages of multi-sourcing cannot be attained. It was also identified that the classification of the structure was a major factor in the case of alternative material selection and introduction.
