Abstract: To analyze the influence of the component size ratio
(matrix/inclusion) on the densification and magnetic property, the equivalent
model of SMCs at particle scale was used for static case. The relation of
porosity, density against the component size ratio δ is
deduced. To calculate the effective permeability of the model, the equivalent
magnetic circuit method and magnetic energy method are proposed and compared.
The results show that the densification and effective permeability are
dependent on the component size ratio. The effect of porosity is even more
pronounced for the effective permeability. In addition, the results of this
model are consistent with the experimental results.
Keywords: Soft magnetic composites, particle sizes ratio, porosity, effective permeability
