Magnetic-aligned, magnetite-filled epoxy composites with ...

2015-1-6  Magnetite powder was used in the study due to its excellent ability to align along the lines of a magnetic field. Furthermore, the magnetite has a relatively low thermal conductivity, which corresponds to a typical industrial filler added to the epoxy resin, which have thermal conductivity typically less than 10 W/m K. Density and the thermal conductivity of epoxy resin and filler are listed ...
