Conductive Composites such as carbon fiber reinforced composites are increasingly used in safety critical aerospace applications. The catastrophic macro structural failure of composite structures initiates from a micro level failure event such as fiber breaks. The ability to detect damage early on can improve the safety level and reliability of com...

... electrode configuration as shown in figure 3 was used. Figure 6 shows typical electrical potential distribution, zero and 60% of delamination length, at the top and bottom respectively. Figure 7 shows the change in resistance as function of delamination depth.. Matrix cracks are also expected to provide similar performance. ...
