Summary

Controlled Structure Technology (CST) has been established as a processing methodology to engineer composite mesostructures. The use of CST with finite element methods (FEM) allows for desk-top design of application-specific composite mesostructures. Accurate performance prediction is dependent on realistic estimates of the actual fiber distribution. X-ray Computed Microtomography (XCMT) and serial sections were used to track the fiber distribution within a CST composite. Reconstructed, 3D XCMT images show that the matrix and fiber-rich regions were continuous and uniform through 1.5 mm3 slices. The 2D sections at 1 mm intervals showed variation in individual fiber location but general consistency in tow-sized groupings. FE-derived damage evolution plots from the serial sections indicate equivalent levels of crack propagation between sections. These results suggest that 2D, FE modeling can be used to simulate 3D crack propagation for CST design considerations.
