Abstract
By using chemical vapor infiltration (CVI) method, 2.5D C/SiC composites were obtained with an average flexural strength of 213.8 MPa, matching the requirements of thermal protection application. Tests of coefficient of thermal expansion (CTE) indicated that The CTE of the 2.5D C/SiC composites remained at a relatively low level (below 2.5×10−6 K−1) in the whole temperature range, which may be attractive for applications that required good dimensional stability. The relationship between the CTE and the temperature was also discussed.
