Stochastic characterisation methodology for 3-D textiles based on micro-tomography

The methodology is applied to the characterisation of a 3-D carbon fabric considered for NASA's Adaptive Deployable Entry Placement Technology (ADEPT) system. Determining geometrical variability in the weave is of importance during the process of setting design margins and risk analysis. Statistical analysis demonstrates strong dependency on the crossover positions for the average trends and correlation data, with a substantially higher variation for the Z-interconnecting tows.
