  • A micromechanics finite element method was used to predict the longitudinal and transverse coefficients of thermal expansion of the following six kinds of composites, T300/5208, P75/934, P75/CE339, C6000/PMR 15, HMS/Borosilicate, P100/2024 Al. The predictions and some other common analytical methods were compared with each other. With experimental data, the predicting accuracy of all these analysis methods was investigated. In all of these methods, the predictions for the longitudinal coefficients of thermal expansion of composites have good agreement with experimental values. However, large discrepancies exist for the transverse coefficients of thermal expansion. The predictions of the Rosen and Hashin(RH) method and micromechanical finite element analysis model are better fit for the experimental values than other analytical methods, and then verify the reliability of the micromechanics finite element method. In addition, the response of the coefficients of thermal expansion for the fiber volume fraction of the six kinds of composites was established by using micromechanics finite element method, the influence of the property ratios of fiber and matrix on the coefficients of thermal expansion was obtained. The results provide the technical foundation for the application of advanced composite materials in aerospace structures.
