Effects of deposition temperature on microstructure of laminated (SiC-C) matrix composites
The microstructure of fiber-reinforced laminated SiC-C matrix composites has been studied using scanning and transmission electron microscopy (SEM and TEM) techniques.

| description | The microstructure of fiber-reinforced laminated SiC-C matrix composites has been studied using scanning and transmission electron microscopy (SEM and TEM) techniques. Different regions of the composites were found to exhibit microstructural differences due to the temperature gradient imposed during composite fabrication by the forced-flow thermal-gradient chemical vapor infiltration process. The matrix layers of alternating Carbon and SiC were found to be thicker but less clearly defined in the higher-temperature regions than in the lower-temperature regions. This feature was found to be more pronounced with increasing distance from the fiber surface. The medium temperature region was found to represent the intermediate point in the microstructural development of this composite. Possible qualitative explanations for the observed microstructural differences are suggested in the context of the temperature gradient and other process parameters employed. |
