4 Focus on composites data How do composite materials vary from metals? Composites materials cannot be created independently from components Composite materials cannot be characterized independent of processing Composites cannot be fabricated, tested and then subsequently formed into a component Composite materials are manufactured by involved multi-step processes Process histories for composites are important, complex and very varied

5 Focus on composites data How do composite materials vary from metals? Performance and property data for composites are similar to that for metals and other materials Mature, well designed materials information management systems sustain composite materials data Some complexity added by conditioning and multi-stage tests (eg CAI) Multiple taxonomies are needed depending on the data Eg Design data: type / matrix / reinforcement / reinforcement structure / layup / conditioning / Test data includes direction, many more examples,

6 Focus on composites data The complexity lies in the processing history Data might be captured at each and every step Property data and processing parameters must be tagged to a specified location in the processing route No one aspect of the data or meta data is more important than another Multiple taxonomies are possible
