Development of Composite Materials for 3d Printing on the Basis of Polyphenylenesulfone

The influence of talc and various polymeric additives on the basic mechanical properties of polyphenylenesulfone was investigated. It was found out that with the increase in the filler concentration there is an increase in stiffness, tensile strength and a decrease in the plasticity of the polyphenylenesulfone. While studying of polymer-polymer composites based on polyphenylenesulfone, high efficiency of polycarbonate as a modifier of impact strength was revealed. An effective method for producing a composite with a high impact strength and a modulus of elasticity has beendeveloped; it is based on the features of the distribution of the filler in the binary system polyphenylenesulfone – polycarbonate. The concentration of the filler in the polycarbonate phaseleads to low values of impactstrength, while its concentration in the phase of polyphenylenesulfone, followed by the introduction of polycarbonate leads to the formation of a high impact and high modulus composite. The samples obtained by 3D printing have high mechanical characteristics.
