Recycle of waste tire rubber in a 3D printed composite with enhanced damping properties

Management of waste tires has become a leading environmental issue due to the global growth in number produced annually. This work is focused on exploring use Ground Tire Rubber (GTR) new class cost-effective, recycled composite materials. A Fused Filament Fabrication (FFF) desktop 3D printer used produce GTR-based material with up 50% wt. rubber filling. ABS as host matrix. Both microscopic and macroscopic characterization printed composites are performed addition baseline composite. Increasing content from 0 % 50 results approximately 260% improvement overall damping properties. Results also indicate average diameter particles increased amount increased. Presumably, specimens larger yielded longer contact lines polymeric Consequently, energy dissipation improved, resulting enhanced properties composites. The capabilities well low-production cost lightweight characteristics presented GTR-filled yield opportunity for application these GTR-reinforced automotive or other industries making wide variety parts where highly valuable.
