Study characteristics of (epoxy-bentonite doped) composite materials

Procedures for preparing ceramic compounds with consisted of bentonite (80 wt %), alumina (10wt %) and silica (10wt %) were examined by solid state reaction technique. The thermal treatment of ceramic sample was studied by X-ray diffraction analysis. The influence of the content of the cordierite and mullite on the gained phase's properties of ceramic compounds specimens was analyzed. We found good insulator with mullite (73.33 wt%) and cordierite (50.10 wt%).The optimum achieved consequences are: Get a ceramic product without any distortion in the it form with the additives under sintered temperature (1250ºC) and gave the maximum diametrical Strength (σD) to 90 MPa. The best results of the break down voltage (24.8Kv) and dielectric strength (8.3Kv/mm). These results allow us to use the ceramic body in energy storage applications. As a second step: the ceramic product was re-grinded and it mixed in different ratio (5, 10, 15 and 20%) with polymer (epoxy) to prepare composites. Some of the physical properties of the product have been tested. The optimal results have been showed for all properties: electrical at the (5and10%) ratio, mechanical the ratio (20%) only and excellent thermal insulation. Depending on the Composite results can be used in the required electrical insulators industry (voltage bushings applications).
