Abstract
The effect of talc and various polymer additives on the basic mechanical properties of polyphenylene sulfone was studied. It was found that with an increase in the concentration of the filler, there is an increase in the elastic strength and a decrease in the plastic properties of polyphenylene sulfone. The physicomechanical properties of various polymer-polymer composites based on polyphenylene sulfone are considered. High efficiency of polycarbonate as a modifier of toughness is revealed. An efficient method has been developed for producing a composite with high values of impact strength and modulus of elasticity, based on the characteristics of the distribution of the filler in the polyphenylene sulfone polycarbonate binary system. It is shown that the concentration of the filler in the polycarbonate phase reduces the impact strength, whereas its concentration in the polyphenylene sulfone phase followed by the introduction of polycarbonate results in an impact-resistant and high modulus composite. Samples obtained by the 3D printing method exhibit high mechanical characteristics.
