摘要	To verify the influence of outgassing effects of polymer matrix in a vacuum environment on the dimensional stability of composite materials, this paper researches the outgassing properties of carbon fiber composite materials on the epoxy and cyanate resin matrixes. Firstly, the relation between expansion coefficient and outgassing coefficient was analyzed theoretically. Then, the test assemblies were designed to accurately measure their changes in the size and the mass. Finally, vacuum tests were carried out three times for several groups of test assemblies according to the demands of satellite environmental test conditions. Experimental results on the sizes and mass of these test assemblies show that the mass loss rates (TML) of epoxy matrix and cyanate resin matrix composite materials are approximately 0.033%-0.06% and 0.014%-0.029% respectively. Moreover, the size changes of epoxy matrix and cyanate resin matrix composite materials are about 2-8 m, and 1-3 m respectively. The mass change of the former is 2 times that of the latter, which means the dimensional stability of two kind of composite materials has different in the vacuum environment. , 2015, Chinese Academy of Sciences.
