Various models are proposed to the composite materials including clusters of reinforcements. In such models, the concentration of reinforcements in the cluster is generally very high or low compared to the outside region of the cluster. However, in realistic composite materials, the difference of concentrations inside and outside of the cluster is relatively small. In the present study, such a low-level clustering of reinforcements is modeled by replacing the cluster with the mixed double inclusion of the first kind by focusing on some reinforcement and smearing out of its surrounding. As a result, the total internal stresses occurring in the composite material are good agreement with those obtained by Taya et.al (JSME A,43-1(2000), pp.46-52.) in the high-level clustering of reinforcements. Moreover, they also agree with those of the random distribution of reinforcement as a limit of low-level clustering,
