Influence of Reinforcing Fillers on the Mechanical Characteristics of Thermoelastoplastic Elastomers Developed for 3D Printing

The influence of reinforcing fillers of different structures on the physical and mechanical characteristics of thermoplastic elastomer (TPE) based on butadiene-styrene elastomer is studied with the aim of further application to additive technologies for the production of elastic materials of a complex geometry. The optimal concentrations for graphene and carbon nanotubes (CNTs) are selected to achieve the maximum reinforcement effect. It is noted that by introducing a combined filler into a polymer matrix, it is possible to obtain a synergistic effect and achieve higher physical and mechanical characteristics due to the different structure of the filler. It is shown that the use of 3D printing with nanoreinforced material allows achieving better physical and mechanical characteristics compared to the standard molding methods.
