The work represents the results of experimental research on the influence of the nanofiller’s nature on
the thermal physical properties of composite materials. Polymer composite materials based on epoxy diane
oligomer ED-20 were modified by 4-aminobenzoic acid. Martens yield temperature was researched and the
glass transition temperature of the developed materials was determined. For the establishment of the
thermal field’s effect on the structural processes of composite materials, the thermal coefficient of linear
expansion of the materials was researched. Due to the necessity of studying the influence of temperature on
physical-chemical processes and transformations in polymer composites, modern thermal analysis methods
were used – differential thermal and thermal gravimetric analysis. Based on the analysis of experimental
data, the optimal content of 4-aminobenzoic acid q 0.10 wt.% was determined per 100 wt.% of the ED-20
oligomer, which leads to the improvement of thermal physical properties of epoxy composite materials
