Improved performance of aeroengines achieved by increasing the operating temperature requires the development of new manufacturing technologies for ceramic matrix composites (CMCs). Manufacturing of CMCs has been simulated using COMSOL Multiphysics. Specialized simulation technologies have been developed to describe the infiltration of molten material into a ceramic perform. The physical phenomena considered in the analysis includes: unsaturated flow, capillary fluid flow, reaction between the fluid and matrix, volumetric changes associated with the fluidsolid reaction, temperature changes associated with the fluid-solid reaction and residual stress development. The resulting simulation allows a more accurate analysis of the process and identification of the significance of the interdependent physical phenomena in the manufacturing process. Application of simulation tools of this type will provide designers with the opportunity to reduce cycle time, increase part yield, and optimize the process window for CMC manufacturing.
