Innovative Quality Control Assessment Methods for Ceramic Matrix Composite (CMC) Components
Agency / Branch:
DOD / NAVY
The fabrication of ceramic matrix composites is a multi-step process requiring careful monitoring and control at each step in the processing cycle. Consistent, high quality components can only be reliably reproduced if a firm foundation is provided by initially insuring the uniformity and consistency of the reinforcing yarns. Although considerable effort has been invested in developing NDE suitable for characterizing green as well as fully consolidated components, much less has been done to characterize the reinforcing yarns. In this Phase II program, we develop and implement in-line testing methods to characterize silicon carbide yarns. Methods are formulated and applied to the yarns as an integrated part of the yarn coating process. Experiments are performed relating various yarn defects to those found in composites. Integration of yarn testing methods into the normal manufacturing process will pay a large dividend in cost reduction, result in more consistent component performance (improved quality), and lead to improved coating processes and product quality.
