3. Multi particle studies Some micrographs of CB reinforced polymer composites published in Choi et al. (2019) can be seen in Fig.5. Since the matrix is an insulator, the particles that form a conducting path are the only ones that contribute to the effective conductivity of the composite. In this work, a 2D composite with circular reinforcing particles is utilized as a case study to compare the different numerical strategies.
