Summary

The effect of fiber distribution on the mechanical behavior of unidirectional fiber composites has been previously established. Using Controlled Structure Technology (CST), a process by which the fiber distribution within the microstructure can be engineered, a series of unidirectional fiber composites were prepared. The mechanical behavior of the CST composites were compared to that of conventionally prepared specimens. In conjunction with the mechanical testing, finite element methods (FEM) were employed to simulate crack propagation through actual digitized microstructures. The FEM simulations allow investigation of a variety of loading conditions for a given engineered microstructure in a cost-effective manner. Combining the ability to engineer microstructures via CST with application-specific stress simulation may allow faster assimilation of ceramic fiber composites as structural materials. This paper reports the preliminary mechanical behavior and simulation results for CST composites which show superior performance to conventionally prepared composites.
