Description: Abstract: The paper presents a new category of magnetic nano-composite materials obtained using magnetic nano-fluids and resins. The samples were prepared using different mixtures of resins and magnetic nano-fluids, with different concentration of magnetic nano-particles. Magnetic fluids, also known as ferrofluids, are ultra stable colloidal suspensions of ferromagnetic particles – e.g. magnetite (Fe3O4) – in various carrier liquids. The ultra fine magnetic particles (of 30 – 150 Å), “integrate” themselves in the structure of the carrier liquid. The colloid stability is assured even in strongly non-uniform magnetic fields. The medium behaves like a quasi-homogeneous strongly magnetizable liquid due to the presence of approximately (1017 – 1018) magnetic particles in one cubic centimeter and combines the properties of magnetic materials with those of fluids, in a rather spectacular way. This research started with the intention to exploit the possibility to achieve some new materials in the context of Nanotechnology Constructions, using the Resin Transfer Molding (RTM) process and the inclusion of nano-fluids, considering the possibility to orient the magnetic nano-particles in magnetic field, as function of the desired properties for the specified applications.
