ABSTRACT

Ultimate strength, softening temperature, and water absorption of the polymer composites based on epoxy resin (type ED-20) with unmodified and modified by ethyl silicate minerals diatomite and andesite are described in this chapter. Experimental results obtained for investigated composites show that one’s containing modified filler have the better technical parameters mentioned above than composites with unmodified filler at corresponding loading. Experimentally is shown that the composites containing binary fillers diatomite and andesite at a definite ratio of them possess the optimal characteristics-so-called synergistic effect. The experimental results are explained in terms of structural peculiarities of polymer composites.
