Effect of the Filler Type on the Properties of Epoxy-Anhydride Compound

The properties of quartz flour, glass balls, and basalt powder as fillers of an epoxy-anhydride compound are studied, and the values of thermal conductivity of filler powders obtained by the probe method on an MIT-1 device according to GOST 30256 are presented. The rheological properties of the components of compounds A and B along with the corresponding mixed compositions on an MCR-92 device are studied. The solidified compounds are characterized by the methods of thermogravimetry and differential scanning calorimetry using an STA 449F3 Jupiter (NETZSCH) device. Using a Fluke PM 6303A RLC meter, the data on the frequency dependence of electrical resistance and the physical and mechanical properties of compounds using a Shimadzu AGSH tension testing machine are obtained. It is shown that the type of the filler determines the properties and formation of the polymer–filler interface as one of the key components of the composite material. The data on the effect of the type of fillers on the operational properties of molding compounds are obtained.
