The hybrid carbon/glass fiber polymer possesses an interesting balance in properties that the drawbacks of one fiber can be balanced out by the virtues of the other. The mixing and clustering of hybrid fibers have a significant effect on the elastic modulus of materials. In this paper, a new micromechanics model is proposed to study the effective elastic modulus of hybrid composite with agglomerated carbon and glass fibers. Three types of fiber dispersion or aggregation forms are proposed to present new relations for a hybrid composite that contains carbon and glass fibers. The Mori–Tanaka method and Voigt and Reuss theory are modified to analyze the aggregation effect of hybrid fibers. The analytical expressions for the effective elastic modulus of hybrid fiber–reinforced composites are defined, which consider the fiber agglomeration effect. It is found that the effective properties are very sensitive to the dispersion state and agglomeration degree of hybrid fibers.
