The
Effect of Ferrite Content on the Thermomechanical and Dielectric
Strength Properties of Epoxy Composite |
Different
concentrations of cadmium ferrite (2%, 5%, 8%, 10% and 15%) were
incorporated into epoxy resin. Cadmium ferrite was prepared by
conventional ceramic technique. Composites are prepared by
mixing the ferrite with epoxy by hand lay - up method at
different percentages. The effect of ferrite content on tensile
strength, hardness, thermal properties such thermal
conductivity, thermal diffusivity and specific heat beside the
dielectric strength were investigated. Using ferrite powders as
filler to form particulate composite could lead to composite
properties improvement. All the measured properties were
improved with the increasing of the filler content. The results
showed the important role of perfect adhesion between the filler
and the polymer on the composite properties. It is found that
the uniform distribution of filler particles in all directions
of composite leads to the improved properties. |
