Research of influence of fillers different nature on the properties of polysulfone and the definition of possibility of applying the composites on their base in the 3D printing

Abstract

The results of studies of the effect of excipients mineral and organic origin of the mechanical properties of polysulfone based on 4,4'-dihydroxydiphenyl and 4,4'-dichlordiphenylsulfone. It has been shown that the introduction of hard fillers is accompanied by increased modulus and reduced ductility of the polymer matrix, the intensity of these effects depends on the concentration, shape and particle size additives. It was revealed that the composites with talc and discrete carbon fibers are characterized by higher mechanical properties. Their test as materials for FDM 3D printing method shows the highest suitability composites with talk for this technology.
