ABSTRACT

In the present investigation, a micromechanics model for predicting thermal expansion coefficients of unidirectional fiber reinforced composites is proposed, and the influence of fiber aspect ratio on the coefficients is also investigated. It is noted that the present model offers a direct prediction of thermal expansion coefficients and can account for the effect of fiber aspect ratio and volume fractions. Moreover, the thermal expansion coefficients of composites with different fiber volume fractions are very sensitive to the aspect ratio of the fiber. The present investigation has the advantage of enhancing the composite performance by adjusting the filler aspect ratio and volume fraction to obtain the desired effective material responses for engineering applications.
