| Abstract: | A Preliminary model for the analvsis thermo-mechanical behavior of interfacialcoating on fibers in unidirectional composites was developed on the solution of thermo-elasticmechanics,The low modulus coating can effectively reduce the interfacial stress caused bydifferent thermal expansion coefficient betweeh fibers and matrix, no matter how high or lowthe expansion coefficients of coatings are in CF/Al and SiC/Ti systems, however,highmodulus coating can decrease the interfacial compressive stress,only when the thermalexpomsion of coating is low. |

| Keywords: | coating thermal stress CF/Al and SiC/Ti composites |
