Production and characterization of composite materials with epoxy resin matrices reinforced with tire rubber and magnetite in different proportions
This work describes the production and magnetic characterization of a compound base on epoxy resin and powdered rubber reinforced with magnetite (𝐹𝑒3𝑂4) poder. Also it is presented the análisis carried out on the components, which are according to the magnetic charging inside the polymeric matrix. the magnetic properties of the material they were made at different temperaturas in a magnetic range from -30000 to 30000 Oe the morphology of both the precursons like the compounds was determined by scanning electron microscopy and structural characterizatin was performed by X- ray diffraction (XRD). The diffraction pattern obtained in the XRD measurements allows us to observe that, with the addition of powdered magnetite in the plastic matrix, an amorphous-crystalline transition is created in the material.
Through the images obtained by SEM, the presence of hematite in the precursor (𝐹𝑒3𝑂4) and irregular size in the samples is observed. The compounds behave like a soft magnetic material and present changes in the variation of the coercive force, both with the increase in temperature and with the percentage variation of magnetite volume in the polymer matrix. The manufactured material can be used in applications where the compound should be easily detectable.
